A man with a mass of 65 kg skis down a friction-less hill that is 4.4m high. At the bottom of the hill the terrain levels out. As the man reaches the horizontal section, he grabs a 19-kgbackpack and skis off a 1.0 m-high ledge. At what horizontal distance from the edge of the ledge does the man land?

Solution Summary

We solve a problem in classical mechanics involving conservation of energy and momentum.

Solution Preview

First we use conservation of energy to compute the man's speed v0 where the hill levels off. At the top of the hill, his potential energy is given by

Mgh = (65)(9.8)(4.4) = 2800 J.
