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

A

u t

B

`(1)/(2) g t^(2)`

C

`(u + g t)t `

D

`u t - (1)/( 2) g t ^(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
Displacement in last t seconds in upward motion will be equal to displacement in first t seconds in downward motion. Therefore, `h = (1)/(2) g t ^(2)`
