1.

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 velocityA. `sqrt(3 V_o)`B. `3 V_o`C. `9 V_o`D. `3//2 V_o`

Answer» Correct Answer - 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`.
