2. a sailor pushes a 100.0 kg crate up a ramp that is 3.00 m high and 5.00 m long onto the deck of a ship. he
exerts a 650.0 n force parallel to the ramp. what is the mechanical advantage of the ramp? what is the
efficiency of the ramp? your response should include all of your work and a free-body diagram.

Mechanical advantage of the ramp =

Efficiency of the ramp = =

Explanation:

i) Mechanical advantage of the ramp =

ii) Efficiency of the ramp = =
