Newton's Third Law of Motion and car collision

AI Thread Summary
During the bumper car collision at Busch Gardens, the force exerted on Jenny's car is directed northward. According to Newton's Third Law of Motion, the magnitudes of the forces that Jenny's car exerts on Betty's car and vice versa are equal. Therefore, the assertion that Jenny's car exerts less force than Betty's car is incorrect. The direction of acceleration for Jenny's car during the collision is also northward. Understanding these principles is essential for grasping the dynamics of collisions.

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!
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
