Question

dockworker applies a constant horizontal force of 80.0N to a block of ice on a smooth horizontal floor. thhe block starts from rest and moves 11.0m in 5.00s. (a) what is the mass of the ice block? (b) if the work stops pushing at the end of the 5.00s, How far does the block move in the next 5.00s?

Answer 1

distance=1/2 a t^2=1/2 force/mass *t^2

do the algebra, solve for mass.

b. No friction? It moves forever at constant velocity. Maybe it ends up in Neverland, who knows.
