MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Vector A has a magnitude of 25 units and points in the positive y-direction. When vector B is added to A, the resultant vector A + B points in the negative y-direction with a magnitude of 13 units. Find the magnitude and direction of B? magnitude v456 unit(s) direction -y Viewing Saved Work Revert to Last Response Submit Answer 2. [-/2.85 Points] DETAILS SERCP9 3.P.008. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A force F 1 of magnitude 7.00 units acts on an object at the origin in a direction 0 = 43.0 above the positive x-axis. (See the figure below.) A second force F2 of magnitude 5.00 units acts on the object in the direction of the positive y-axis. Find graphically the magnitude and direction of the resultant force F 1 + F2. magnitude units direction . counterclockwise from the +x axis F
