Question: Three people pull simultaneously on a stubborn donkey. Jack pulls eastward with a force of 63.3 N, Jill pulls with 76.1 N in the northeast direction, and Jane pulls to the southeast with 137 N. (Since the donkey is involved with such uncoordinated people, who can blame it for being stubborn?)
Part A: Find the magnitude of the net force the people exert on the donkey.
Please give actual answer for above question.
