Jenny and Betty are having a great time at Busch Gardens riding the Ubanga Banga bumper cars. Jenny, who is traveling southward in her bumper cars, aims her cars toward Betty, who is traveling northward in her bumper car. The cars collide and briefly come to a stop. What is the direction of the force exerted on Jenny's car during the collision and what is the direction of the acceleration of Jenny's car during the collision?
I really do not understand this. Please explain!!
Jenny's car is accelerated in the same direction as the force on her car. Since Jenny was traveling southward before the head-on collision, and came to a stop, her force received and acceleration were northward.
