Question

Part A A 1500 kg car drives around a flat 200-m-diameter circular track at 40 m/s What is the magnitude of the net force on the car? Express your answer to two significant figures and include the appropriate units. Fan Value Units Submit My Answers Give Up Part B What is the direction of the net force on the car? O The net force points opposite the direction of moton The net force points to the center of the circle O The net force points away from the center of the circle The net force ports the direction of motion O The net force is zero

Explanation / Answer

A)   centripetal force F = mv^2/r

                                 = 1500 * (40)^2 /200

                                 = 12000 N = 1.2 * 10 ^4 N

B) this centripetal force always acts towards the center of the circle
