Three people pull simultaneously on a stubborn donkey. Jack pulls directly ahead of the donkey with a force of

99.9N,Jill

pulls with

66.3N

in a direction

45\\\\deg

to the left, and Jane pulls in a direction

45\\\\deg

to the right with

121N

. (Since the donkey is involved with such uncoordinated people, who can blame it for being stubborn?)\ Determine the magnitude

F

of the net force the people exert on the donkey.\ What is the direction

\\\\theta

of the net force? Let

0\\\\deg

define straight ahead, with positive angles to the left and negative angles to the right. Express

\\\\theta

as an angle with a magnitude between

0\\\\deg

\

F=

\

N

\ and

90\\\\deg

.
