1. Three ropes are tied in a knot as shown in the figure. One student pulls on rope A with 1.0 N of force, and another student pulls on rope B with 7.0 N of force. How hard (magnitude) and in what direction must you pull on rope C to balance the first two pulls? Give the direction by specifying the angle (clockwise or counterclockwise) of the pull with the direction of rope A. Rope BX Final formula: Rope A X =1:ON Fx 7.ON 7.0u sin 30° = F = -6,9 7.0 cos 30°- F=1 Rope B = Sin 30= 120° Knote %3D Rope A 1.ON %3D Rope C 1,01 ー69 ROpe A l.0 Required steps: )Choose-axes- 2) Find vectors components 3) Write the equation to balance the forces 4) Find the magnitude and direction of the force that pulls rope C Yope B
