Centripital acceleration

  1. Nov 7, 2008 #1
    1. The problem statement, all variables and given/known data

    A car is negotiating a flat circular curve of radius 50 m with a speed of 20 m/s. The maximum centripetal force (provided by static friction) is 1.2 × 104 N. What is the centripetal acceleration of the car?

    2. Relevant equations

    MAc = MV^2/R

    3. The attempt at a solution

    20^2 / 50 = 8 m/s^2 ?

    Not sure, but I think you're right. I have no idea what the second sentence actually means, but it might just be a red herring. Cent acc is just velocity squared over radius, and they gave you that in the first sentence.
