A rope is attached to a 50.0-kg crate to pull it up a frictionless incline at constant speed to a height of 3 meters. A diagram of the situation and a body diagram are shown below. Note that the force of gravity has two components (parailet and perpendicular component); the parallel component balances the applied force and the perpendicular component balances the normal force.
