In a slapshot competition, a player strikes a hockey puck with a stick, causing the puck to travel in a straight line on a smooth ice surface. The mass of the puck is 160.0 g and the coefficient of friction between the puck and the ice is 0.150. If 50.0 m from the starting point, the speed of the puck is measured to be 16.5 m/s, what was the initial speed of the puck?
