Problem

Two horses pull horizontally on ropes attached to a stump. The two forces = 1310 N and 2 that they apply to the stump are such that the net (resultant) force has a magnitude equal to that of 1 and makes an angle of 901 with 1. The two horses are pulling horizontally on ropes attached to a stump. The first horse is pulling to the southwest and the second horse is pulling to the east. The resultant force R and the force of the first horse have the same magnitude and make a right angle.

Find the magnitude of .

Find the direction of (relative to ).
