Estimate the mass of the block of ice

Reference no: EM13512653

A dockworker applies a constant horizontal force of 89.0 n to a block of ice on a smooth horizontal floor. The frictional force is negligible. The block starts from rest and moves a distance 10.0 m in a time 5.20 s.

A- What is the mass of the block of ice?

B- If the worker stops pushing at the end of 5.20 s, how far does the block move in the next 4.90 s?
