A 2.50 kg block is pulled horizontally 4.30 m over horizontal ground by a 22.0 N applied force. Ifμk = 0.56, find:
(a) the work done by the applied force;
(b) the work done by friction;
(c) the heat pro- duced;
(d) the change kinetic energy of the block;
(e) the final speed of the block if it started at 3.5 m/s.
