A shell is fired at an angle of 30^ to the horizontal with velocity 196 ~m / s . The time of flight is [ 30^ = 1 2 = 60^ ]

Options

  1. A10 ~s
  2. B16.5 ~s
  3. C20 ~s
  4. D6.5 ~s

Correct answer

C. 20 ~s

Step-by-step solution

We know the time of flight for a projectile is given by: t= 2 u g On placing given values in the above equation: t= 20 (196 ~m / s ) (30^ ) (9.81 ~m / s ^2 ) =20 ~s
