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.
