2. You are helping a friend move. Consider two boxes which have masses in factors ofm; one of mass 6m and the other of mass 7m. The coefficient of static friction between the two boxes is very large. The coefficient of static friction between the boxes and the floor is 0.7 and the coefficient of kinetic friction is 0.1. You place the large box on top of the small box and slide them down a 1m high ramp out of the truck. The ramp directionless because it is covered with wheels. The box slides down this ramp smoothly-onto the horizontal grass with coefficient of kinetic friction is 0.142857142857143. How far (in meters) will the boxes slide before they stop?
