1. a 50 N crate is pulled up a 5-m inclined plane by a worker at aconstant velocity. if the plane is inclined at 37 degrees to thehorizontal and there exists a constant frictional force of 10Nbetween the crate and the surface what is the force applied by theworker?
2. a 20-N crate starting at rest slides down a rough 5.0m long rampinclined at 25 degrees with the horizontal. 20J of energy is lostto friction. what will be the speed of the crate at the bottom ofthe incline?
