What is the car's (centripetal) acceleration?

Question

A race car rounds a curve at 53 m/s. The radius of the curve is 405 m, and the car's mass is 670 kg. (Assume the car's speed remains constant. Take the radially inward direction to be positive.)

What is the car's (centripetal) acceleration?

Answer 1

Fc = mv^2/r

m = 670kg

V = 53 m/s

r = 405m

Fc = 670 * 53^2/405

Fc = 4646.9 N
