Question
Three people pull simultaneously on a stubborn donkey. Jack pulls directly ahead of the donkey with a force of 98.1 N, Jill
pulls with 90.7 N in a direction 45° to the left, and Jane pulls in a direction 45° to the right with 115 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:
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:

A cube of mass mj = 6.2 kg is sitting on top of a second cube of the same size and mass m, = 1.1 kg while both are in free fall.
Ignoring any air resistance, what is the magnitude of the normal force with which the bottom cube is acting on the top cube?
magnitude of the normal force:
N
