Centripetal force stunt driver problem

  1. Nov 3, 2014 #1
    1. The problem statement, all variables and given/known data
    A stunt driver for a movie needs to make a 2545kg car skid on a large, flat, parking lot surface. The force of friction between the tires and the concrete surface is 1.75x10^4N and he is driving at a speed of 24m/s. As he turns more sharply, what radius of curvature will he reach when the car just begins to skid? (Ans: 83.8m)

    2. Relevant equations
    Fc=(m)(v)^2/r

    3. The attempt at a solution
    1.75x10^4N=(2545kg)(24m/s)^2/r
    1.75x10^4N=1,465,920/r
    0.011937m=r
