2. (25 points) A small block of mass m is released from rest on a frictionless track. At the bottom of the track it goes into a box of mass M. The box, with the block, moves along a frictionless surface a distance S. Starting at the point marked 0 there is friction between the box and the surface with coefficient of friction . If the box is to stop right at the point a distance L from the point 0, what must be the height H? Box H oi S Free Body Diagrams (If appropriate). Law or Definition H 11 = a (144) cos
