Problem 2E

To extricate an SUV stuck in the mud, workmen use three horizontal ropes, producing the force vectors shown in ?Fig. E4.2?. (a) Find the x- and y- components of each of the three pulls. (b) Use the components to find the magnitude and direction of the resultant of the three pulls.

Step-by-Step Solution:
