A dockworker applies a constant horizontal force of 85.0N to a block of ice on a smooth horizontal floor. The frictional force is negligible. The block starts from rest and moves a distance 11.0m in a time of 5.10s. What is the mass of the block of ice? If the worker stops pushing after 5.10s , how far does the block move in the next 5.00s ?
