Question: Three people pull simultaneously on a stubborn donkey. Jack pulls directly ahead of the donkey with a force of 68.1 N, Jill pulls with

Three people pull simultaneously on a stubborn donkey. Jack pulls directly ahead of the donkey with a force of 68.1 N, Jill pulls with 64.5 N in a direction 45 to the left, and Jane pulls in a direction 45 to the right with 163 N. (Since the donkey is involved with such uncoordinated people, who can blame it for being stubborn?) Determine the magnitude F of the net force the people exert on the donkey. What is the direction 0 of the net force? Let 0 define straight ahead, with positive angles to the left and negative angles to the right. Express 0 as an angle with a magnitude between 0 : 90. F = N 0 =
