Three people pull simultaneously on a stubborn donkey. Jack pulls directly ahead of the donkey with a force of 77.3 N77.3 N , Jill pulls with 85.7 N85.7 N in a direction 45° to the left, and Jane pulls in a direction 45° to the right with 147 N147 N . (Since the donkey is involved with such uncoordinated people, who can blame it for being stubborn?) Determine the magnitude ?� of the net force the people exert on the donkey. ?=�= NN What is the direction ?� of the net force

Determine the magnitude ?� of the net force the people exert on the donkey.
?=�=
NN
What is the direction ?� of the net force? Let 0∘0∘ define straight ahead, with positive angles to the left and negative angles to the right. Express ?� as an angle with a magnitude between 0∘0∘ and 90∘.90∘.
?=�=
