Part (c) The post is to be pulled out of the ground using two ropes A and B as shown. i) The rope A is subject to a force of P1 = 400 N and is directed at 35° from y axis as shown in figure. If the resultant force acting on the post is to be 1200 N vertically upward along the y axis, determine the force P2 acting on rope B. ii) If suppose the forces acting on rope A is P1 = 400 N and on robe B is P2 = 380 N, deter- mine the resultant force and the direction measured from the positive x axis. The direction of both Pj and P2 is given in the figure. P1 P2 35° 45°- B.
