A dockworker applies a constant horizontal force of 71.0N to a block of ice on a smooth horizontal floor. The frictional force is negligible. The block starts from rest and moves a distance 10.5m in a time of 4.80s. What is the mass of the block of ice? If the worker stops pushing after 4.80s, how far does the block move in the next 5.40s?
