183.33... Watts.
Power = (energy used) / (time to use that much energy) = 40/5 = 8 watts
mass of the object (times) gravitational acceleration (times) height the object reaches.
Any amount will do.
It depends on the magnitude of the force and the mass of the object

The force required to lift the object is much less than otherwise. One might see this surprising. How the use of a ramp can decrease the force required to lift an object? The answer is that the distance the object has to moved is longer. This means that the work done in both cases is the same.(assuming there is no resistive forces) (Work done = Force x distance moved in the direction of the force) In practice however, due to friction, the total work done may actually be greater, but the decrease in the applied force is indeed worth it. A system of pulleys also uses this principle, as well as hydraulic systems.

The cost to remove an object from a cat's stomach depends on what procedure is required to remove the object, and the cost of the animal hospital.
