Provided that the parachute has the same surface area for both of the parachutist's, the 200kg man will hit the ground first due to the extra weight from the heavier man.
what is it you want to know, please be more specific
Person on the airplane: Crate will appear to be dropping straight down. Person on the ground: Crate will be curving in the direction the plane is moving.
With parachutes and air resistance in the mix, the heavier object probably hits the ground first. If they were simply released from altitude and fell freely, without parachutes or air resistance, then they hit the ground at the same time, no matter how their masses or weights compare.
The weight of the crate is acting downward on the ground and the ground is exerting a force equal to the weight of the crate upward on the crate.

F=ma F=200kg*9.80665 m/s² = 1980 N
891.8 newtons.
You should have friction between the box and the ground, the force you used to push it, the mass of the object, and gravity. The resistance of the air is neglibible. This should be all the forces on an object on flat ground.
It goes across.
Nowhere, there is no such thing as "preciitate calcite".
It really depends. On the person and the type of crate. I think you need to be alot more specsific about that one im afraid. Also depends on the size of the crate. Type of animal..... You get the point. Sorry.
get a food crate/barrel at the store and drag stuff from the top to the ground and they feed themselves
