Aball is dropped from an upper floor, some unknown distance above your apartment. as you look out of your window, which is 1.50 m tall, you observe that it takes the ball 0.150 s to traverse the length of the window. 1) determine how high above the top of your window the ball was dropped. ignore the effects of air resistance. (express your answer to three significant figures.)

The ball is dropped at a height of 9.71 m above the top of the window.

Explanation:

Given:

Now using equation of motion in one dimension we have

Let u be the velocity of the ball when it reaches the top of the window

then

Now u is the final velocity of the ball with respect to the top of the building

so let t be the time taken for it to reach the top of the window with this velocity

Let h be the height above the top of the window

real, smaller and upside-down.   so the answer should be b.
