A 33.0 kg box initially at rest is pushed 5.95 m along a rough, horizontal floor with a constant applied horizontal force of 145 N. If the coefficient of friction between box and floor is 0.300.
find:
the work done by the applied force
the increase in internal energy in the boxfloor system due to friction
the work done by the normal force
the work done by the gravitational force
the change in kinetic energy of the box
the final speed of the box
