Answer: A 60 g golf ball is dropped from a level of 2 m high. It rebounds to 1.5 m. Energy loss will be 0.29J
Explanation: To find the correct answer, we have to know more about the Gravitational potential energy.
<h3>What is gravitational potential energy?</h3>- The energy possessed by a body by virtue of its position in gravitational field of earth is called gravitational potential energy.
- The gravitational potential energy of a body at a height h with respect to the height h will be,
- Expression for gravitational potential energy loss will be,
- The total energy before the ball dropped will be,
- The total energy after when the ball rebounds to 1.5m will be,
- The total energy loss will be,
Thus, we can conclude that, the energy loss will be,0.294J.
