What is the maximum force that keeps the car moving in its circular path at the maximum speed v max ? A. static friction force B gravitational force B. gravitational force C. normal force D. tension force
Test #1 A car is rounding a flat, unbanked curve with radius R. The coefficient of friction between the tires and road is μ s . Find the maximum speed of the car. That is, express v max in terms of μ s , g , and R . μ R s max A. v g = max s B. v gR μ = max s C. v gR μ =
