What is the maximum speed

  1. Jan 16, 2005 #1
    A car enters a horizontal, curved roadbed of radius 50 m. The coefficient of static friction between the tires and the roadbed is 0.20. What is the maximum speed with which the car can safely negoitate the curve if the radius of the curve 2.00 x 10^2?


    please help

    Start by reading the problem carefully. It makes no sense to say "roadbed of radius 50 m" and then say "the radius of the curve 2.00 x 10^2".
