- 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 betweenthe two boxes is very large. The coefficient of static friction between the boxes and thefloor is 0.7 and the coefficient of kinetic friction is 0.1. You place the large box on top ofthe small box and slide them down a 1m high ramp out of the truck. The ramp isfrictionless because it is covered with wheels. The box slides down this ramp smoothlyonto the horizontal grass with coefficient of kinetic friction is 0.142857142857143. Howfar (in meters) will the boxes slide before they stop?A 10.1 kg box is released on a 49.9° incline and accelerates down the incline at 0.07 m/s².
