Answer: 2000Joules
Explanation:
Potential energy is the energy possessed by a body by virtue of its position. A body thrown upward covered a particular height(h) and under the action of gravity(g)
Potential energy = mass × acceleration due to gravity × height
Given mass = 10kg g = 10m/s² height = 20m
Potential energy= 10×10×20
Potential energy = 2,000Joules
Potential energy
