A dockworker applies a constant horizontal force of
80.0 N to a block of ice on a smooth horizontal floor. The frictional force is negligible. The block starts from rest and moves
11.0 m in 5.00 s. (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? .
