A body is projected at angle `30^(@)` to horizontal with a velocity `50 ms^(-1)`.Its time of flight is

A body is projected at angle 30° to horizontal with a velocity 50 msl. Its time of flight is (g=10m//s^(2))

A body is projected at angle 30° to horizontal on a planet with a velocity of 80 ms^(-1) its time of flight is 4 seconds then acceleration due to gravity on that planet is

A body is projected at angle 30° to horizontal with a velocity 50 ms^(-1) .In the above problem range of body is m. [g = 10 ms^(-2) ]
