# Question: A hockey puck with a mass of 200 g and

A hockey puck with a mass of 200 g and an initial speed of 25.0 m/s slides freely to rest in the space of 100 m on a sheet of horizontal ice. How many forces do nonzero work on it as it slows:

(a) (1) none, (2) one, (3) two, or (4) three? Explain.

(b) Determine the work done by all the individual forces on the puck as it slows.
