Velocity of a stone projected, 2 second ...

Velocity of a stone projected, `2` second before it reaches he maximum height, makes angle `53^(@)` with the horizontal then the velocity at highest point will be

A

`20 m//s`

B

`15 m//s`

C

`25 m//s`

D

`80//3 m//s`

Text Solution

Verified by Experts

The correct Answer is:
B

Two second before maximum height `v_(x)=gx`

`tan53=(20)/(V_(x)),v_(x)=15m//s` at maximum height
`v=v_(x)=15m//s`
