I need help with the question below.

2. A 4.38 kg rock lls ll meters to the ground om the side ofa cli'. {a} Hon.r much potential energy is liberated from this rock fall: {i} on Earth? (ii) on the moon? [You will need to rst determine rlittle gr for the lunar surface, for Earth we use the usual magnitude of g = 9.81mi'sz. Show your work when calculating rgr for the moon.] {b} How much kinetic energy is gained by this rock fall just before impact: (i) on Earth? {ii} on the moon? {Assume no energy losses due to air resistance on Earth.) (c) Use your answers from {h} to determine the rock's nal (impact) velocity: (i) on Earth, (ii) on the moon. (Assume no energy losses due to air resistanoe on Earth.) (d) Iftile rock's nal (impact) velocity on Earth was only 94.1% of the velocity you determined in part {c}, then how much energy was lost due to air resistance? (e) How long does it take the rock to fall: {i} on Earth? (ii) on the moon? (Assume no energy losses due to air resistanoe on Earth.) {f} 1What is the power of this energy transfer, for the 1rock fallr described above= where gravitational potential energy is being converted into kinetic energy: (i) on Earth? (ii) on the moon? (Assume no energy losses due to air resistance on Earth.) {g} Show how 'little g1 for the surface acceleration on Earth versus the moon can he used to determine the ratios of the results in (a), (e) and (
