Want this question answered?
For an object moved along a vertical line near Earth's surface, the work required is given by: Work = m g Δh Where m is the object's mass (3.08 kg in this case), g is the acceleration due to gravity near Earth's surface (9.81 m/s2) and Δh is the change in the object's height (10.3 m in this case).
The height is irrelevant. The energy required depends on the height; the force does not. The weight of an object, and therefore the force required to lift it, is mass x gravity - about 500 Newtons.The height is irrelevant. The energy required depends on the height; the force does not.

It creates a mechanical advantage and reduces the force required to lift or move an object.
The acceleration due to gravity (9.8 meters/sec.^2) * mass of object.

lift him/her by the bottom!
Faster-moving air exerts less pressure, so there will be force (lift) generated by the air below the object. This is the principle of powered heavier-than-air flight. The object will have a area of low(er) pressure in top than air underneath, causing lift. This is cause by the air on top being stretched out and having lower density or pressure then the bottom. If there is enough lift to counteract the weight of the object, the object will lift off the ground.
