A box of mass m has a force F applied an angle to the horizontal. The block starts at rest and is on a smooth surface. a) Find an expression for the Work done on the box by each force that acts on the box as it moves in initial distance d. b) Find an expression for the net work done on the box while moving a distance d. c) Find an expression for the speed of the box after it moves a distance d. d) The box now encounters a section of the surface that is rough and has a coefficient of friction of . The applied force is suddenly removed. 1. Using Newton's Laws and kinematics find the distance traveled by the box coming to rest. Using the Work Energy Theorem find the distance traveled by the box coming to rest. 11. e) What is the average power exerted by the applied force for the initial distance d traveled by the box. Use the diagram below as an illustration for the following problems. E LL F 0 d F H₂ A box of mass m has a force F applied an angle to the horizontal.
