With what speed should a body be thrwn upwards so that the distances traversed in 5th second and 6th second are equal ?

`58.4 m//s`

`49 m//s`

`sqrt(98) m//s`

`98 m//s`

Text Solution

Verified by Experts

The correct Answer is:

It happens when in this time interval velocity becomes zero in vertical motion
`rArr u/g=5rArr u=5xx9.8=49 m//s`
