1. The problem statement, all variables and given/known data A 1500 kg automobile travels at a speed of 110 km/h along a straight concrete highway. Faced with an emergency situation, the driver jams on the brakes and slides to a stop. a) What is his stopping distance on dry pavement (mu = 0.85)? b) What is his stopping distance on wet pavement (mu = 0.60)? 2. Relevant equations My instructor gave me this equation to use to solve the problem: -µFN=max 3. The attempt at a solution I first converted km/h to m/s which came out to be 0.533. I then plugged my numbers into the formula: -0.85FN=1500(0.533) and came out with this answer: FN= -940.6 for a and FN= -1332.5 for b Im not sure where I messed up, but if anyone could help me that would be great! Thanks!
