The diagram shows a mass after it slides down the inclined plane. There is a static
friction coefficient of 0.5 and a kinetic friction coefficient of 0.3 between the box
and the incline. The angle of the incline is 30 degrees , and the box has a mass of 4
kg . The starting height at the top of the ramp is 0.8 meters (and the distance along
the ramp is 1.6 meters ).
A) Prove, with numbers, that the box, if let go from rest at the top of the ramp
*will* start to slide down?
B) Calculate the magnitude of the energy “lost” due to the work done by friction
(in Joules).
C) Calculate the speed of the box at the bottom of the ramp (in m/sec).

A block of mass m = 2.1 kg slides down a 36 ° inclined ramp that has a height h = 3.1 m. At the bottom, it hits a block of mass M = 7.1 kg that is at rest on a horizontal surface. Assume a smooth transition at the bottom of the ramp. If the collision is elastic and friction can be ignored, determine the distance the mass m will travel up the ramp after the collision.
