1. The problem statement, all variables and given/known data An object takes 18m to stop due to friction. Assume no skidding. If the coefficient of static friction is 0.35, what is the initial velocity of the object? 3. The attempt at a solution I have looked at the Normal vs Frictional force equation and I have looked at the three equations involving initial, final velocity and acceleration. I've gone through my notes and skimmed through couple of other book but now help.
