Atennis ball is hit into the wall with a speed of 26 m/s. if it rebounds with a speed of 24 m/s, how much energy was lost in the collision? mass of tennis ball = 0.059 kg a) 6 joules b) 1 joule c) 3.0 joules

C) 3.0 joules

Explanation:

The kinetic energy of the ball is given by:

where

m = 0.059 kg is the mass of the ball

v is its speed

At the beginning, v = 26 m/s, so the initial kinetic energy is

after the rebound, v = 24 m/s, so the final kinetic energy is

So, the energy that was lost is

object 2 because all the other ones are wrong

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
