3. A hockey referee drops a 175 g hockey puck from rest vertically downward from a height of 1.05 m above the ice surface. m (a) Determine the gravitational potential energy of the puck relative to the ice before the referee drops it. (b) Calculate the change in gravitational potential energy of the puck as it drops from the referee's hand to the ice surface. (c) Calculate the work done on the puck by gravity as the puck travels from the referee's hand to the ice surface.
