A 1500 kg car drives around a flat 200-m-diameter circular track at 25m/s. What are the magnitude and direction of the net force on the car? What causes this force?

As the object is moving in a circle, the net force on the object is centripetal force.

Centripetal force = (mass * velocity²) / radius

mass = 1500 kg

velocity = 25m/s

radius = 0.5 * diameter of circle = 200/2 = 100m

Centripetal force = (1500*25²) / 100 = 9375 Newtons
