A race car rounds a curve at 53 m/s. The radius of the curve is 450 m, and the car's mass is 665 kg. (Assume the car's speed remains constant. Take the radially inward direction to be positive. Indicate the direction with the sign of your answer.)
(a) What is the car's (centripetal) acceleration?
(b) What is it in g's? (enter value to 3 decimal places)
(c) What is the centripetal force acting on the car?
