Two prospectors are pulling on ropes attached around the neck of a donkey that doesn’t want to move. One
prospector pulls with a force of 25 lbs, and the other pulls with a force of 50 pounds. If the angle between the
ropes is 30 degrees, then how much force must the donkey use in order to stay put? (The donkey knows the
proper direction in which to apply his force.)
