A particle is thrown vertically upwards....

A particle is thrown vertically upwards. If its velocity is half of the maximum height is `20 m//s`, then maximum height attained by it is

A

25 m

B

30 m

C

35 m

D

40 m

Text Solution

Verified by Experts

The correct Answer is:
D
Let `H`: maximum height

`O` to `A: (20)^(2)=u^(2)-2g.H/2 …(i)`
`O` to `B: 0=u^(2)-2g H …(ii)`
`H=40 m `
