Assignment:
A 2.50 kg block is pulled horizontally 4.30 m over horizontal ground by a 22.0 N applied force. If μk = 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.
