A dockworker applies a constant horizontal force of 83.0 N to a block of ice on a smooth horizontal floor. The frictional force is negligible. The block starts from rest and moves a distance 1.0 m in a time 4.80 s . What is the mass of the block of ice? If the worker stops pushing at the end of 4.80 s , how far does the block move in the next 5.70 s ?
