A stone is droped from a window It hits the ground after 4 s How high is the window?

Answer 1

speed due to gravity 10 m/s, d=s x t = 4s x 10 = 40 m

The above answer is 100 percent wrong.

distance s, in a gravitational field, is calculated as follows:

s = (v0 * t) + 1/2 * a * t^2

where

v0 is the initial velocity, if any

a is the accelaration due to gravity, or 9.8 meters per second squared at the earth's surface

t is the time in seconds

Since the initial velocity is zero (the stone is dropped, not thrown) the first expression results in zero, the first expression may be dropped, and the equation is simplified.

s = 1/2 a * t^2

s = 9.8 / 2 * t * t

s = 78.4 meters

Answer 2

The height of the window can be calculated using the equation h = 0.5 * g * t^2, where h is the height, g is the acceleration due to gravity (9.8 m/s^2), and t is the time taken (4 s). Plugging in the values, h = 0.5 * 9.8 * 16 = 78.4 meters. So, the height of the window is 78.4 meters.
