3.Mount the first two pulleys as in procedure 1, mount a third pulley on the 220° mark and suspend a mass of 150 g over it. Draw a vector diagram to scale and determine graphically the direction and magnitude of the resultant. This may be done by adding the third vector to the sum of the
Calculations: 1.Calculate the resultant in procedure 1 by solving the third side of theforce triangle algebraically. Find the magnitude of the resultant vector by using the law of cosines and the direction from the law of sines. Compare your result with that obtained in procedure 1. How do these predicted results compare with your experimental finding inprocedure 2?
