During practice, a hockey player passes the puck to his coach who is 6.5 m away. The puck, which has a mass of 0.180 kg, was initially at rest. The hockey player exerts a constant 48.2-N force as his stick pushes the puck 0.18 m. Include only the puck in the system and assume the friction between the ice and the puck is negligible. What work must the coach do on the puck to stop it?
