When a body is projected simultaneously from the top of the building with different initial horizontal velocity which of the two will hit the ground first?

Ignoring air resistance, the horizontal component of velocity has no connection
with, and no effect on, the vertical component. Two bodies that leave the top of
the building simultaneously with the same vertical velocity hit the ground at the
same time, regardless of their horizontal velocities or their masses.
That's the same as saying that a bullet fired horizontally from a gun and a bullet
or a stone dropped from the gun's muzzle at the same instant hit the ground at
the same instant. Strange but true.

Why does building foundations have a large horizontal area of contact with the ground?
this is because when the area of contact between the ground and the building increases the pressure exerted by the building will be less for the same force.
What does a spirit level tell?
A spirit level tells us the level of the surface we are working on ie. building a wall etc, is true, i.e. vertical or horizontal.

THE QUESTION: 2) A 5 kg object is thrown from the top of a building, 275m aboce some level ground. It is released at a speed of 45 m/s, initially along the horizontal direction. (A) What are the magnitude and direction of its velocity at impact on the ground below (B) what momentum does it have at impact (C) What KE does it have just before impact (D) What is the average force during the impact?
What is progressive horizontal evacuation?
Horizontal evacuation is when you have to move horizontally on the same floor to get to safety. You may have different steps to take in order to get out of the building.

What is a AV-keystone?
it is when, as if you are looking up at a tall building, a projected image hits a surface at an angle and creates a trapezoid shape i.e. the width recedes as it gets higher - nearly all video projectors have vertical keystone correction and more expensive professional ones have horizontal also.
