a 28Kg rock approaches the foot of a hill with a speed of 15 m/s.This hill slopes upward at a constant angle of 40degrees above thehorizontal. The coefficents of static and kinetic friction betweenthe hill and the rock are .75 and .20.

A) use energy conservation to find the maximum height the rock will reach?

B) Will the rock remain at rest, at it's highest point, or will itslide back down?

C) If the rock does slide back down, find it's speed when itreturns to the bottom of the hill.
