Homework Statement
Two ships, one moving 15 degree west of north with a speed 25 mi/h., the second moving 25 degree south of west with a speed 20 mi/h. relative to water pass each other. Find the velocity of the second ship relative to the first ship (magnitude and direction).
Homework Equations
V1 + r = V2
V2 - V1 = r
The Attempt at a Solution
I want to confirm on this.
My approach is using this relation.
V1 + r = V2
and so V2 - V1 = r, where r is the velocity we are looking for of our problem.
Then I will take components, x and y, and find sqrt(x^2+y^2) and direction tan-1 y/x
