F(x)=93.3 +73.1cos45 +181 cos 45 =
F(y)=73.1 sin45 -182sin 45 =
F=sqrt{F(x)²+F(y)²}=
Three people pull simultaneously on a stubborn donkey. Jack pulls eastward with a force of 93.3 N, Jill pulls with 73.1 N in the northeast direction, and Jane pulls to the southeast with 181 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.
