Question 8) A dockworker applies a constant horizontal force of 85.0 N to a block of ice on a smooth horizontal floor. The frictional force is negligible. The block starts

from rest and moves15.0 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 5.00s?
