The bowling ball would need less because it has more of a Gravitational pull to the ground than the tennis ball does. The letters represent force = mass and acceleration. I hope this helps ✨✨
Answer:
98J
Explanation:
Given parameters:
Mass of rock = 5kg
Height = 2m
Unknown:
Work done = ?
Solution:
The amount of work done is given as:
Work done = Force x distance
Work done = Weight x height
Work done = mgH
Now insert the parameters and solve;
Work done = 5 x 9.8 x 2 = 98J
True, they represent the direction of motion
