1. The problem statement, all variables and given/known data
Consider the two vectors r1 and r2 shown in the diagram. The magnitudes of the two vectors are: r1=6.1 and r2=9.3. The vectors directions relative to the x axis are defined by the angles: θ1=25 degrees and θ2=51 degrees.
What is the magnitude of the vector R=r1+r2?
What is the magnitude of the vector r=r2−r1?
What is the angle between R and the x axis? (in degrees)
What is the angle between r and the x axis? (in degrees)
2. Relevant equations
Picture is attached
3. The attempt at a solution
For vector R, I think the magnitude is 15.4
For vector r, I think the magnitude is 3.2
But how do i figure out the other 2?
Thanks a million once again!
