Homework Statement
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)
Homework 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.
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?
