Three people pull simultaneously on a stubborn donkey. jack pulls directly ahead of the donkey with a force of 79.9 n , jill pulls with 73.3 n in a direction 45° to the left, and jane pulls in a direction 45° to the right with 137 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.
