Answer:
6J
Explanation:6J
Using the potential Energy formula;
Potential Energy = mass * acceleration due to gravity * height
If a ball is thrown 6m above the ground. Its total energy at that point is 12 J
Get the mass of the ball
12 = m * 9.8 * 6
m = 12/58.8
m = 0.204kg
The height of the ball halfway = 6/2 = 3m
Potential energy half way = mgh
Potential energy half way = 0.204 * 9.8 * 3
Potential energy half way = 6J
