Question

when a ball is thrown up vertically with vwlovity v it reaches the maximum height of h if one wishes to triple the maximum height then the ball should be thrown with velocity

Answer 1

your answer is with 3v

Answer 2

H = v^2 / (2g)

H ∝ v^2

H1/H2 = (v1 / v2)^2

H1 / (3H1) = (v1 / v2)^2

v2 = v1√3

Ball should be thrown with a velocty of 1.732v₀
