Physics (AS & A Level) · Oct / Nov 2024 · Paper 11 · Question 13

An object is dropped from rest on the Earth from a height of 2.0 m. The same object is dropped from rest on the Moon from twice the height. The acceleration of free fall on the Moon is approximately 16% of the value on the Earth. Assume that there are no resistive forces acting on the object. What is the ratio (speed of the object just before hitting the surface on the Earth)/(speed of the object just before hitting the surface on the Moon)?
