**1. The problem statement, all variables and given/known data**

Trying to find momentum of A. False starting over the initial part of this question.

A is travelling at 15m/s in a straight line.

Picture below is a bit crude.

**2. Relevant equations**

pA= m*u’

**3. The attempt at a solution**

B = u cosθ i, u sinθ j

Is A= 15 cos65 i, 15 sin155 j ?

Any help would be much appreciated.
