A dockworker exerts a constant horizontal force of around 86.0 m to a block of ice on a smooth horizontal floor. The frictional force is negligible. The block begins from rest and moves a distance 12.5 m in a time 4.50 s.
Part A: Determine the mass of the block of ice?
Part B: When the worker stops pushing at the end of 4.50 s, determine how far does the block move in the next 5.20 s?
