A gun of muzzle speed 10 m/s sits 40 m above a horizontal plane. The firing angle for greatest range on the plane is about: (Take $g = 10 m / s^{2}$ )

Answer:

18.40

Solution:

$θ = \frac{1}{2} cos^{- 1} (\frac{400}{100 + 400}) = \frac{1}{2} cos^{- 1} (0.8) = \frac{36.8 7 ^{\circ}}{2} = 18. 4^{\circ}$ .
