The animation shows the top view of a string tied from a smooth peg to a 0.5 kg puck resting on an air hockey table. The puck is given an initial tangential velocity such that it travels at constant speed in a circle around the peg, with time in seconds and position in meters. After one second, the air to the table is turned off and the puck eventually stops. What is the magnitude of the work done by friction on the puck?
0, because the puck is traveling in a circle.
