A dockworker applies a constant horizontal force of 72.0 N to a block of ice on a smooth horizontal oor. The frictional force is negligible. The block starts from rest and moves a distance 12.5 m in a time of 5.50 s.(a) What is the mass of the block of ice? (b) If the worker stops pushing after 5.50 s, how far does the block move in the next 5.70 s? [87.1 kg, 25.9 m]
