When a ball is thrown up vertically with velocity `v_0`, it reaches a maximum height of h. If one wishes to triple the maximum height then the ball should be thrown with velocity

A

`sqrt(3 V_o)`

B

`3 V_o`

C

`9 V_o`

D

`3//2 V_o`

Text Solution

Verified by Experts

The correct Answer is:
A
`H_(max) prop u^2` :. `u prop sqrt(H_(max))`
i.e., to triple the maximum height, ball should be thrown with velocity `sqrt(3) u`.
