A 68.2 kg base runner begins his slide into second base while moving at a speed of 4.33 m/s. He slides so that his speed is zero
qwelly [4]

Answer:

147.653J = W_f

Explanation:

We know that:

E_i - E_f = W_f

where E_i is the initial energy, E_f is the final energy and W_f is the energy lost due to friction.

so:

\frac{1}{2}MV^2-0 = W_f

Where M is the mass and V is the velocity of the runner, so:

\frac{1}{2}(68.2kg)(4.33m/s)^2 = W_f

147.653J = W_f

Answer: D

Explanation:
Let us examine the given actions to see which ones generate heat and sound energy from mechanical energy.

A) Stretching a string.
The mechanical stretching creates tension in the string, which is released when the tension is removed. The generation of thermal or sound energy is minimal or negligible.

B) Squeezing a sponge ball
The sponge ball experiences compressive loading. This generates minimal or no heat and sound energy.

C) Throwing a ball upwards in the air
Air friction generates minimal or no heat at low velocities. At low velocities the pressure waves are too small to generate sound.

D) Striking a hammer on a nail.
A tremendous amount of force is applied over a small area to generate very high stresses that are in the plastic zone. A high amount of thermal energy is generated and the localized disturbance of the air generates audible sound.
This is the correct situation.

7. What two controls on a car cause a change in speed? What control causes a change in<br> velocity?
Tju [1.3M]

-- A change in speed can be either speeding up or slowing down. These effects can be caused by the gas pedal or the brake pedal.

-- Velocity is made of the car's speed and direction. These can be changed by the gas pedal, the brake pedal, or the steering wheel.
