What is the mass of the block of ice

Reference no: EM132103697

Question: A dockworker applies a constant horizontal force of 73.0 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 13.0 m in a time 4.50 s.

(a) What is the mass of the block of ice?----- I found this to be 56.9kg and got it right.

(b) If the worker stops pushing at the end of 4.50 s, how far does the block move in the next 4.20s ? ------ I tried using [distance=0.5at^2] but it says its wrong. how do you do this question?
