Unformatted text preview: 3.2. CHAPTER 3, PROBLEM 2 193 3.2 Chapter 3, Problem 2 Problem: A man driving his classic 1955 Chevy at a speed v o slams on his brakes and comes to a stop after skidding a distance x f . During the skid, his deceleration, a , is constant. The combined mass of the man and his Chevy is m and the coefficient of kinetic friction between the car’s tires and the road is μ . (a) Solve for a as a function of v o and x f . (b) Determine the time it takes for the car to stop, t f , as a function of x f and v o . (c) Determine μ as a function of a and gravitational acceleration, g . (d) Compute the values of a , t f and μ for v o = 72 km/hr and x f = 25 m. F = − ma i v = v i x ........................................................................................................................................................................................................................................................... ....
