PROBLEM 1 A 40 Kg block slides down a 30 rough inclined plane. The block starts from rest at a height of 4m (top of the plane). The coefficient of kinetic friction Hx between the block and the plane is 0.2. Find a) The energy of the block at the top of the plane b) The work done by friction along the plane. c) The speed of the block at the bottom of the plane (using conservation of energy)
