When a ball is thrown up vertically with velocity v₀ , it reaches a maximum height of h . If one wishes to triple the maximum height then the ball should be thrown with velocity

Options

  1. A3 v₀
  2. B3 v₀
  3. C9 v₀
  4. D3 / 2 v₀ .

Correct answer

A. 3 v₀

Step-by-step solution

As v^2=u^2+2 a s u^2 s or v₀^2 s ( u=v₀ ) For given condition, u^ 2 3 s From eqn. (i) and (ii), u^ 2 v₀^2 =3 u^ = 3 v₀
