A2 kg ball thrown vertically upward and another 3 kg ball projected with certain angle ( 90) both will have same time of flight. Then the ratio of their maximum heights is

Options

  1. A2: 3
  2. B3: 2
  3. C3 : 2
  4. D1: 1

Correct answer

D. 1: 1

Step-by-step solution

For vertical upward projection, T ₁= 2 u ₁ ~g For projectile motion, T ₂= 2 u ₂ ~g aligned & T ₁= T ₂ 2 u ₁ ~g = 2 u ₂ ~g u ₁= u ₂ & H ₁ H ₂ = u ₁^2 / 2 ~g u ₂^2 ^2 2 ~g = ( u ₁ u ₂ )^2=1: 1 aligned
