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

A

ut

B

`(1)/(2)"gt"^(2)`

C

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

D

`(u+gt)t`

Text Solution

Verified by Experts

The correct Answer is:
B
Distance convered in last t second of ascent = distance covered in first 1 second of descent
`=0+(1)/(2)"gt"^(2)`
