Assuming that acceleration due to gravity is 9.8 m/sec^2, then the required height is 0.75 metres.
Potential energy refers to the energy of an object that is released as kinetic energy when it falls back to the ground. When a stone is dropped from a height of 5m, its speed when it hits the ground is 9.9 m/s.

The average height of a window is 3'-7" and the width is 3'.
Depends on the window
Windows differ in height and style by make and model, but the average car window height is19.5-inches. Standard window heights on vans and SUV's have a standard height of 21.9-inches.
Measure the height and width of the window in inches. Next, multiply the height of the window by the width of the window. Then divide that number by 144 to get square feet.

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
1/10 th of floor height
Object Window...
For a smaller window such as a 36" X 36", the average height above the floor is about 32" to 36". For a taller window, it may be as little as 20-22" above the floor.
any object that has form and volume is measured in meters.examples:length of a table, height of a man, height of the basketball hoop, the length of the track, the width of the window.
