Three people pull simuianeously on a stubborn donkey. jack pulls directly ahead of the donkey with a force of 88.5 n, jill pulls with 99.5 n in a direction 45° to the left, and jane pulls in a direction 45° to the right with 189 n. (since the donkey is involved with such uncoordinated people, who can blame it for being stubbom? ) find the magnitude of the net force the people exert on the donkey. number 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 number
