5. Imagine dropping a soccer ball. The first bounce will be highest,
and each bounce after that will be lower until the ball stops
bouncing. Describe the energy changes that take place and
explain how energy is conserved.

The compressed ball then has kinetic energy which causes it to

rebound, but to a lesser height than the original because of the

energy expended in the stretching and the friction.

--

The process is then repeated.

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
