work done by gravity = force * distance
= - m g h
force in same direction as motion on the way down = + m g h
here
m = 0.058 kg
g = 9.81 m/s^2 or whatever your class uses or whatever planet you are on
h = 7.02 meters
A tennis player hits a 58.0 g tennis ball so that it goes straight up and reaches a maximum height of 7.02 m .
Part A
How much work does gravity do on the ball on the way up?
Part B
How much work does gravity do on the ball on the way down?
