Sagot :

Answer:

Explanation:

1. GPE only as the ball is not moving.

GPE = mass * gravity * height

= 2kg * 9.8m/s^2 * 40m

= 784J

2. Both KE and GPE as the ball is moving.

GPE is the same as 1 at 2*9.8*40 = 784J

KE = 1/2 * mass * velocity^2

= 1/2 * 2kg * (5m/s)^2

= 25J

3. KE only as the bottom is on the ground.

KE = 1/2 * 2kg * (10m/s)^2

= 100J
