The formula for position is x = 1/2at2.
If we start at a distance of 40 feet, and gravity is 32 feet per second squared.
So in this instance:
40 = 1/2 (32) t2
40 = 16 t2
40/16 = t2
2.5 = t2
t = 1.58 seconds

A 0.650 kg basketball is dropped out of a window that is 6.46 m above the ground. The ball is caught by a person whose hands are 1.32 m above the ground. How much work is done on the ball by its weight?

A 1.50 kg bal is dropped from a roof top 12.0m above the ground How long does the ball take to reach the ground?
1.56 seconds
How come when a ball is dropped it doesnt reach the original height it was dropped from?
Some of the energy is lost (dissipated) in the process of rebounding. Also, air resistance can slow down the ball a bit.
Which is faster to reach ground feather or ball in free fall?
In vacuum they reach ground exactly at the same time. In a medium other than vacuum the ball will reach ground first.
Which is the force that pulls a ball to the ground after being dropped?
Gravity.

Will a16 lb bowling ball and a 10 lb bowling ball dropped together reach the ground together?
Yes... Its not the weight but the force of gravity
What would happen if a ball was thrown and there was no gravity?
They would reach the ground at the same time and whoever dropped them would die of suffocation.
A ball dropped from a window strikes the ground 2.00 seconds later how high is the window above the ground?
As , s = ut + 1/2 a t2 , since a ball is dropped , the equation is modified as h = ut + 1/2 g t2 Therefore , h = 0 x t + 1/2 x 9.8 x 22 [ u = 0 ,since the ball is at rest] h = 19.6 meters Height of the window = 19.6 meters

If you drop a ball from 10 feet and 5 feet which will reach the ground first?
The ball which you drop from 5 feet will reach the ground first.
A child drops a ball from a window. The ball strikes the ground in 3.0 seconds. What is the velocity of the ball the instant before it hits the ground?

If a ball is dropped from a height of 128 meters how high did the ball reach after the 7th bounce?
3 ft
What will drop first a big ball or a small ball?
Both will reach the ground at the same time if they were dropped at the same time in a vacuum. This is a well proven fact that the mass has no effect on the acceleration of an object in a free fall in a vacuum.
