Question

36. A stone is released from a height of 10 m. Its potential energy at the highest point is 1000 J.
Find the following: (Take g = 10 m/s-)
i. Its potential energy at height 5 m from the ground
11. Its kinetic energy at a height of 5 m from the ground
The sum of kinetic and potential energies at a height of 5 m from the ground
iv. The kinetic energy just before impact
V.
Compare the final answer values of (iii) and (iv) and state which law is
responsible for the observation.​
