1. The problem statement, all variables and given/known data
here's the problem
A 68.5 kg skater moving initially at 2.40 m/s on rough horizontal ice comes to rest uniformly in 3.52 s due to friction from the ice.
2. Relevant equations
F= ma
3. The attempt at a solution
I'm sure this equation is reliant on finding the acceleration, but I really don't know how to do that when time (instead of distance) is our given variable
anyone know what I'm missing?
