I push a 10 kg crate from rest up an incline plane. The plane is 5m long and makes an angle of 25 degrees with the ground.
(a) if I lose 100 J of energy to friction sliding the box to the top, how much work is required to push the crate to the top of the incline?
(b) What is the ideal mechanical (Mi) advantage of this plane? (Mi= s/h where s is displacement up inclined plane and h is vertical displacement
(c) What is the efficiency of the plane? (Efficiency= Ma/Mi)
