Question
Three people pull simultaneously on a stubborn donkey. Jack pulls directly ahead of the donkey with a force of 70.9 N, Jill pulls
with 76.7 N in a direction 45° to the left, and Jane pulls in a direction 45° to the right with 159 N. (Since the donkey is involved
with such uncoordinated people, who can blame it for being stubborn?) Find the magnitude of the net force the people exert on
the donkey.
magnitude of the net force:
N
What is the direction of the net force? Express this as the angle from straight ahead between 0° and 90°, with a positive sign for
angles to the left and a negative sign for angles to the right.
direction of the net force:
