Answer:

a) Vi = 137.2 m/s

b) h = 960.4 m

Explanation:

a)

In order to find the initial speed we will use first equation of motion:

Vf = Vi + gt

where,

Vf = Final velocity = 0 m/s (since ball stops at highest point)

Vi = Initial Velocity = ?

g = - 9.8 m/s² (negative sign for upward moyion)

t = time interval = 14 s

Therefore,

0 m/s = Vi + (-9.8 m/s²)(14 s)

Vi = 137.2 m/s

b)

Now, we use second equation of motion to find height (h):

h = Vi t + (1/2)gt²

h = (137.2 m/s)(14 s) + (1/2)(-9.8 m/s²)(14 s)²

h = 1920.8 m - 960.4 m

h = 960.4 m

A football player throws a football 30 meters in 2.5 seconds, divide 30 by 2.5 and get 12.

An object's speed, also known as "v," is the amount by which its position changes over time or by how much it changes per unit of time, making it a scalar number.  

The instantaneous speed is the upper limit of the average speed as the duration of the time interval approaches zero. The average speed of an item in a period of time is equal to the distance traveled by the object divided by the duration of the period. Velocity and speed are not the same thing.

The parameters of speed are time divided by distance. The metre per second (m/s), the SI measure of speed, is the most widely used unit of speed in daily life.

Answer:

Choice d: support force (normal force) on the cat and the weight of the cat are equal in magnitude.

Explanation:

The cat in this question is stationary. As a result, the acceleration of this cat will be zero. By Newton's Second Law of Motion, the net force on this cat will also be zero.

If the floor is level, there will be two forces acting on this cat:

For the net force to be zero, these two forces need to balance each other. For that, they need to have the same magnitude and point in opposite directions. Therefore, the magnitude of the support force (normal force) will be equal to the magnitude of the weight of this cat.

Forces may be applied to pendulums to counteract friction when the goal is to maintain the pendulum's motion over an extended period of time, or to reduce the effects of external disturbances that may interfere with the motion of the pendulum.

Friction is a force that acts to slow down the motion of a pendulum, leading to a decrease in amplitude over time. In addition, external forces such as air resistance, which acts in the opposite direction to the motion of the pendulum, can also cause a decrease in amplitude. To counteract these forces, additional forces can be applied to the pendulum.

One common method for reducing the effects of friction on a pendulum is to use a device called a "driving force" or "motor". This device applies a force to the pendulum at the right time and in the right direction to maintain or increase the amplitude of the pendulum's motion. This method is used in many types of clocks and other precision instruments that rely on the motion of a pendulum.

Another method is to use an electromagnet to attract and release the pendulum at precisely the right time to keep its motion going. This method is often used in high-precision pendulum clocks and scientific experiments.

The system described by the transfer function G(s) = -co² s² + 2a + w², with a damping ratio of 1.3 and a natural frequency of 0.5, has an overdamped unit step response. So, the correct option is (E)

The transfer function of the system is given as G(s) = -co² s² + 2a + w², where co represents the damping ratio, a represents an arbitrary constant, and w represents the natural frequency of the system. We are given that the natural frequency is 0.5 and the damping ratio is 1.3.

To determine the type of unit step response, we need to analyze the damping ratio (co) in relation to the critical damping value (co_critical).

The critical damping ratio (co_critical) is defined as the value where the system is on the threshold between being overdamped and underdamped. It is given by the formula co_critical = 2 * sqrt(a * w²).

In our case, the natural frequency (w) is 0.5, so we can calculate co_critical as follows: co_critical = 2 * sqrt(a * 0.5²).

Since the damping ratio (co) is given as 1.3, we can compare it with co_critical to determine the type of unit step response.

If co > co_critical, the system is considered overdamped (Option E).

If co = co_critical, the system is considered critically damped (Option D).

If co < co_critical, the system is considered underdamped (Option C).

Based on the given values, we can determine that the system is overdamped (Option E) because the damping ratio (1.3) is greater than the critical damping ratio.

Land rover ads used to claim that their vehicles could climb a slope of 45 Degrees.

Hence, the correct option is D.

We can use the following formula to calculate the minimum coefficient of static friction required for the Land Rover to climb a slope of 45 degrees.

tan θ = coefficient of static friction

Where θ is the angle of the slope.

For a slope of 45 degrees, we have

tan 45 = coefficient of static friction

By simplifying, we get

The average kinetic energy of all the atoms and molecules that make up a substance is referred to as a c. temperature.

Temperature is the term that is used to describe total average kinetic energy of all the atoms and molecules that make up a substance. The average thermal or kinetic energy of the particles in a system is measured by temperature. It illustrates how hot or cold a thing is to a certain degree.

In terms of energy transfer, such as heat, radiation refers to the emission and propagation of electromagnetic waves or particles. The phenomenon referred to as greenhouse effect is when certain gases in the atmosphere trap heat, warming the surface of the Earth. Whereas, heat represents a thermal energy that is transferred from one system or item to another as a result of a temperature differential.

(A) The direction of VC is clockwise since both links are rotating in the clockwise direction.

(B) The acceleration of link C (AC) has a magnitude of 1.5 rad/s² and is in the clockwise direction.

(A) To calculate the direction and magnitude of VC (velocity of link C), we need to consider the rotational velocities of both link 2 and link 3.

Link 2: Rotating at 1.5 rad/s clockwise (CW)
Link 3: Rotating at 0.75 rad/s clockwise (CW)

Since both links are rotating in the same direction, we can add their rotational velocities:
VC = 1.5 rad/s + 0.75 rad/s = 2.25 rad/s

The direction of VC is clockwise since both links are rotating in the clockwise direction.

(B) To calculate the direction and magnitude of AC (acceleration of link C), we need to consider the rotational accelerations of both link 2 and link 3.

Link 2: Accelerating at 2.0 rad/s² clockwise (CW)
Link 3: Accelerating at 0.50 rad/s² counterclockwise (CCW)

Since link 2 and link 3 have opposite directions of acceleration, we will subtract the smaller acceleration from the larger one:
AC = 2.0 rad/s² - 0.50 rad/s² = 1.5 rad/s²

To determine the direction of AC, we look at which link has a larger acceleration. In this case, link 2 has a larger acceleration in the clockwise direction, so AC's direction is also clockwise.

In summary, the velocity of link C (VC) has a magnitude of 2.25 rad/s and is in the clockwise direction. The acceleration of link C (AC) has a magnitude of 1.5 rad/s² and is in the clockwise direction.

The equivalent resistance of a circuit reduces as more parallel resistors are added, but the circuit's overall current increases. Additional branches via which charge can flow are comparable to more resistors being added in parallel.

A circuit can have parallel or series connections connecting two or more electrical components. The circuit is referred to as a parallel circuit when all of the devices are linked utilizing parallel connections. Each device is located in a distinct branch of a parallel circuit. Branch lines indicate that there are numerous paths for charge to move via the external circuit.

A single resistor located in a single branch will be contacted by each charge moving through the external circuit's loop. A charge choose which branch it will take on its way back to the low potential terminal when it reaches the branching site or node.

It was made clear that increasing the number of resistors in a parallel circuit has the very surprising effect of reducing the total resistance. The addition of a second resistor in a different branch creates a second avenue for charge to travel through the circuit's primary area of resistance because there are numerous ways for it to do so.

By increasing the number of branches, the resistance will reduce, which will increase the pace at which charge flows (also known as the current).
