A 985 kg car is driving on a circular track with a constant speed of 25.0 m/s. The circumference of the track is 2.75 km. a. Why does a passenger in the car feel pulled toward the outside of the circular path?

b. Describe the force that keeps the car moving in a circle.

c. Find the centripetal acceleration of the car.

d. Find the centripetal force on the car.
