1. The problem statement, all variables and given/known data Find Particle A's speed with respect to Particle B. I am given: Particle A: (15i - 10j) or 18.03 m/s angle A: -33.69 degrees Particle B: (5i + 15j) or 15.81 m/s angle B: 71.57 degrees (Both angles with respect to x axis) 2. Relevant equations Had there not been any angles, I know I would have to subtract the two vector quantities but I don't know how to solve it with angles. 3. The attempt at a solution I know the k components, found by using Pythagorean Thereom, do I simply subtract k(A) - k(B) ? that would be 37.88 k. Is this correct?
