Momentum Change and Impulse in Colliding Balls

[soupastupid]

Homework Statement

There are two balls traveling and they collide. How do there momentum change.
What is the impulse done to ball B by ball A.

Homework Equations

delta momentum = 0
impulse = ?

The Attempt at a Solution

the first part

i think its C

becuz A is moving up and B is moving down
the horizontal movement didnt change

and so the impulse from ball A to ball B
must be pointing DOWN right?

and the answer must be B ??

right?

right?

Right!

(btw, impulse and change-of-momentum are the same thing )

I would like to clarify a few points about the concept of momentum change and impulse in colliding balls.

Firstly, momentum is a physical quantity that describes the motion of an object and is defined as the product of an object's mass and velocity. In a collision between two objects, the total momentum of the system is conserved, meaning that the sum of the momentums of the two objects before the collision will be equal to the sum of their momentums after the collision. This is known as the law of conservation of momentum.

In the scenario described, two balls are traveling and they collide. The momentum of each ball will change as a result of the collision. The change in momentum of an object is known as impulse, which is defined as the product of the force applied to the object and the time interval over which the force acts. In this case, the impulse done to ball B by ball A can be calculated by determining the force applied by ball A to ball B during the collision and the duration of the collision.

It is important to note that the direction of the impulse will depend on the direction of the force applied during the collision. If ball A exerts a force on ball B in a downward direction, then the impulse will also be in the downward direction. However, the direction of the impulse may not necessarily be the same as the direction of the change in momentum. This is because the change in momentum is influenced by the initial momentum and the final momentum of the object, while the impulse is influenced by the force applied during the collision.

In conclusion, the momentum of the two balls will change as a result of the collision and the impulse done to ball B by ball A can be calculated by determining the force applied during the collision. The direction of the impulse will depend on the direction of the force applied during the collision. I would recommend further research and understanding of the concepts of momentum and impulse in order to fully comprehend the scenario described.
