12. (a) When a hockey player makes a wrist shot, he applies a reasonably constant force to a puck for a
distance of between 0.8 to 1.4 m. Explain why the work energy theorem may be used to analyse the resulting
motion of the puck.
(b) It would be reasonable to assume that a hockey player, using the stick, is able to exert a force of 60.0 N on
a puck for a distance of 1.00 m. The mass of a puck is approximately 0.200 kg. Determine:
(i) The amount of work done on the puck.
(ii) The amount of kinetic energy in the puck immediately after release.
(iii) The final speed of the puck. Check to ensure that the answer is reasonable!
