Adockworker 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 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?
