(1) A dockworker applies a constant horizontal force of 88.0N to a block of ice on a smooth horizontal floor. The frictional force is negligible. The block starts from rest and moves a distance 13.0m in a time of 4.70s .
a) What is the mass of the block of ice?
b) If the worker stops pushing after 4.70 s , how far does the block move in the next 5.10?
