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
- A2: 3
- B3: 2
- C3 : 2
- 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
