If a ball is thrown vertically upwards with speed `u`, the distance covered during the last `t` second of its ascent is

`1/2 "gt"^2`

`ut-1/2 "gt"^2`

`(u - "gt")t`

Text Solution

Verified by Experts

The correct Answer is:

The distances covered by the ball during last t second of its upward motion = Distance covered by it in 1st t second of its downward motion.
`h =ut - 1/2 "gt"^2` [upward]
`h = 1/2 "gt"^2 ` [ downward]
