Homework Statement
A dockworker applies a constant horizontal force of 72.0N to a block of ice on a smooth horizontal floor. The frictional force is negligible. The block starts from rest and moves a distance 10.0m in a time 4.50s. If the worker stops pushing at the end of 4.50 , how far does the block move in the next 5.70s?
Homework Equations
v = at
x = x0 + v0t + 1/2at^2
The Attempt at a Solution
I realized this is only a kinematics problem, but I keep getting the wrong answer. I got 32.1m, but the answer is 25.3m. I did v=at, plugging in 0.987654321*5.70 then multiplied this answer by 5.70. What am I doing wrong??
