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 box-floor 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
