Question

Ball A of mass 0.55 kg has a velocity of 0.65 m/s east. It strikes a stationary ball, also of mass 0.55 kg. Ball A deflects off ball B at an angle of 37° north of A's original path. Ball B moves in a line 90° right of the final path of A. Find the momentum (in kg m/s) of Ball A after the collision.

Answer 1

Is there a picture you can supply? If ball B moves 37° north from the east, and 90° right of the final path of A, A must move 127° north from the east, that is in the north west direction. But the both A's and B's momenta would have a positive component in the north direction which would violate the law of conservation of momentum since at the beginning there was no component of momentum going north.

Answer 2

@ivancsc1996 is right

Answer 3

This is my understanding, that A is the one deflected north and B is 90° right/clockwise of the deflection.
