A rope that is directed 30° above the horizontal, is exerting a 10.0-N force to pull a 5.0-kg block at constant speed along a 5.0-m horizontal floor. After drawing the free-body diagram find:
the magnitude of the normal force from the floor on the block
the magnitude of the force of friction
the work done by the rope's force
the increase in the thermal energy of the block-floor system
the coefficient of kinetic friction between the block and floor.
