I need help how to show the expression / equation for this problem:

A dockworker applies a constant horizontal force of (F) to a block of ice on a smooth horizontal floor. The frictional force is negligible. The block starts from rest and moves a distance (x) in a time (t1).

If the worker stops pushing at the end of (t1), how far does the block move in the next (t2)?
