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?
Answered by MathMate
The vertical component of the force is Fsin(θ) where F is the force on the rope, and θ is the angle with the horizontal.
