Problem B2. A small box of mass m = 1.50 kg starts from rest and glides down a smooth, frictionless hill from a height h = 2.00 m to the base, where it meets a rough plank of mass M = 5.00 kg that is resting on the frictionless horizontal ground surface. Due to the friction between the box and the plank, its speed is reduced until, at a certain moment, it begins to move together with the plank as if they were a single object. %3D M Figure B2. Problem diagram B2 c) Calculate the work done by the friction forces present in the problem.
