A body is released from the top of a tower of height h takes time ‘t’ to reach the ground. After time 't'2, the height from the ground is…..

For a freely falling body  h=12gt2Let ‘y’ be the distance travelled by it after  't'2 s∴y=12gt22 =1412gt2=h4 ∴ The height of the body from the ground is  h1=h−y=h−h4   =3h4.
