A dock worker applies a constant horizontal force of 81.0 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 13.0 m in a time of 5.20 s .
Required:
a. What is the mass of the block of ice?
b. If the worker stops pushing at the end of 5.00 s, how far does the block move in the next 5.00 s?
