By the Way, guys, this is based on the equation H= -16t2+vt+s

How long does it take to hit the ground from 28000 feet high?
The answer will depend on what "it" is, and on what its initial velocity is.
Will a ball drop rest reach the ground quicker than the one lunched from the same height but with and initial horizontal velocity?
No. What counts in this case is the vertical component of the velocity, and the initial vertical velocity is zero, one way or another.
An arrow is shot straight up at an initial velocity of 250ms How long will it take to hit the ground?
This is a velocity question so u need to use uvaxt
If a ball is dropped from a building that is 200 feet above ground What will the velocity be when t is 1?
height(s)=1/2(u+v)t 200=1/2(0+v)*1v=400ft/secu = initial speedv=final speed
A brick is released with no initial speed from the roof of a building and strikes the ground in 2.00 s encountering no appreciable air drag How tall in meters is the building?
19.6m
What is A football kicked off at an angle 20 from the ground reaches a maximum height of 4.7 m What is the initial velocity of the kick?
initial velocity of the kick = 28.06 m/s
Which information is needed to find the time a projectile is in motion?
The object's initial distance above the ground The object's initial velocity

What is the rock's approximate velocity just prior to hitting the ground?
To answer this question one would need to know the rock's initial height and velocity.
When a wet ball is thrown to ground it has more velocity after it hits ground than at throwing Explain Why?
This result is because the wet ball carries more inertia to weight ratio before hitting the ground , it then compresses, loses some of the liquid weight, becomes lighter, and because of the initial inertial force, can therefore leave the ground at a greater velocity
What do you you need to know to determine how far a projectile travels horizontally?
initial velocity, angle of launch, height above ground When a projectile is launched you can calculate how far it travels horizontally if you know the height above ground it was launched from, initial velocity and the angle it was launched at. 1) Determine how long it will be in the air based on how far it has to fall (this is why you need the height above ground). 2) Use your initial velocity to determine the horizontal component of velocity 3) distance travelled horizontally = time in air (part 1) x horizontal velocity (part 2)

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.
How much time will it take for the coin to hit the ground -16 plus 96 plus 112?
The answer depends on its initial velocity and the height from which its fall to the ground is measured.
