Thank you for your responses. This was a question posed to me by a friend of mine who rock climbs. He inferred that the distance of the fall could be calculated using the force, mass and gravitational constant. Is it correct to say that the energy spent to stop will be the same for different...

Homework Statement A rock is dropped from x(meters) height. The rock weighs 68 kg, and its force at impact with the ground is 15 kiloNewtons. If the acceleration due to gravity is 9.8m/s^2, what is the distance/height the rock has fallen? Homework Equations F=m*a...
