I need some assistance as to how they got their answer? A 15-kg rock is dropped from rest on the earth andreaches the ground in 1.75 s. When it is dropped from the sameheight on Saturn's satellite Enceladus, it reaches the ground in18.6 s. What is the acceleration due to gravity on Enceladus?[0.0868 m/s^2]
