##### Reference no: EM13240805

A dockworker applies a constant horizontal force of 72.0N to a block of ice on a smooth horizontal floor. The frictional force is negligible. The block starts from rest and moves a distance 12.5m in a time of 5.10s .

What is the mass of the block of ice? in kg

If the worker stops pushing after 5.10s , how far does the block move in the next 4.50s ? in m
