A person applies a constant horizontal force of 85.0 N to a block of ice on a smooth horizontal floor. Neglect friction. The block starts from rest and moves 11.5 m in 4.50 s.
1. What is the mass of the block of ice?
2. If the person stops pushing at the end of 4.50 s, how far does the block move I the next 4.50 s?
