An ice skater glides on one skate, across a thin film of water that forms on the ice surface due to the pressure exerted by the skater. However, the water lm that supports the skate also causes deceleration (so does drag on the body of the skater with the air, but consider only the skate and water film here). The skater has a mass of 55 kg. The skate contact surface is 29 cm long and 3 mm wide. The...
