Answer:
1) Potential energy of the ball just before the kick was taken = 0J
2) The potential energy of the ball just before it was caught = 58.8 J
Explanation:
1)Since the height of the ball is 0m on the ground, the potential energy of the ball just before the kick was taken is 0 J
2) The mass of the ball, m = 1.5 kg
Acceleration due to gravity, g = 9.8 m/s^2
the height of the ball, h = 4 m
The Potential Energy = mgh
The potential energy of the ball just before it was caught = 1.5 x 9.8 x 4
The potential energy of the ball just before it was caught = 58.8 J
