Newton's Third Law of Motion and car collision

Click For Summary

Homework Help Overview

The discussion revolves around a scenario involving a collision between two bumper cars, focusing on Newton's Third Law of Motion. Participants explore the forces and accelerations involved during the collision.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants discuss the direction of forces during the collision, the relationship between the magnitudes of forces exerted by each car, and the direction of acceleration. There is an emphasis on understanding Newton's Third Law and its implications in this context.

Discussion Status

Some participants have expressed uncertainty about their reasoning, particularly regarding the magnitudes of the forces. Others have confirmed the equality of the forces as per Newton's Third Law, indicating a productive exploration of the concepts involved.

Contextual Notes

There appears to be some confusion regarding the application of Newton's Third Law, particularly in relation to the forces exerted by the two cars during the collision.

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 car, aims her car toward Betty, who is traveling northward in her bumper car. The cars collide and briefly come to a stop.

1)What is the direction of the force exerted on Jenny's car during the collision?
2)What can you say about the magnitude of the force that Jenny's car exerts on Betty's car versus the magnitude of the force that Betty's car exerts on Jennifer's car?
3)What is the direction of the acceleration of Jenny's car during the collision?

I have no idea if I'm right but...
1) Northward
2) Jenny's car exerts less force than does Betty's car.
3) Northward

1 & 3 are correct; 2 is not. Better look up Newton's 3rd law.
 
So there magnitude of the forces must be equal because the law states: "For every action, there is an equal and opposite reaction."
 
Right!
 
Thank you for all your help!
