Answer:
By the law of conservation of mechanical energy, in the absence of any drag, when the rock falls towards the ground, the potential energy gets converted to kinetic energy. Once the rock hits the ground, it does not move. This is because, the energy is dissipated as sound or heat (to the environment). The total energy remains conserved. Only the form of energy changes.
Answer: B

Answer:
3.56 m
Explanation:
As the object falls from height h, and then compresses the spring a distance of 0.66m, its initial potential energy is converted into elastics energy of the spring.
Let g = 9.81m/s2. Knowing that the total change in potential height is h + d, we have the following equation
