A stone is thrown at an angle to be horizontal reaches a maximum height H . Then the time of flight of stone will be

Options

  1. A2 H g
  2. B2 2 H g
  3. C2 2 H g
  4. D2 H g

Correct answer

B. 2 2 H g

Step-by-step solution

H= u^2 ^2 2 g and T= 2 u g T^2= 4 u^2 ^2 g^2 T^2 H = 8 g T= 8 H g =2 2 H g
