How should I approach this question:
You are driving at a constant velocity of 25 m/s.
You have antiques in the back of your pick-up truck.
You see a giant hole in the road, 55 m ahead of you.
Coefficients of friction for the antiques: μs=0.6 and μk=0.3.
Can you stop without the antiques sliding and being damaged? (Hint: You're not trying to stop in the shortest possible distance.)
All I have found so far was the acceleration if you were to stop right before the giant hole. The value I calculated is a = -5.68 m/s2. I can't figure out what to do with the coefficients of static and kinetic friction, however.
Thank you.
