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