A construction worker attempts to pull a stake out of the ground by pulling on a rope that is attached to the stake and makes an angle of 60.0 degrees with the horizontal. Then worker exerts a force of 125 newtons on the rope. What is the magnitude of the upward component of the force acting on the stake?
1 answer
