The figure below shows a system for lifting up crates from ground level to a certain height. The crate 1 has a mass of 12.7 kg and the crate 2 has a mass of 9.40 kg. If there were no friction, what force F would be necessary to maintain a constant velocity while pulling the crates up the fixed inclines?
