The angle of projection for a projectile to have same horizontal range and maximum height is :
The angle of projection for a projectile to have same horizontal range and maximum height is :
- $\tan ^{-1}(4)$
- $\tan ^{-1}\left(\frac{1}{4}\right)$
- $\tan ^{-1}\left(\frac{1}{2}\right)$
- $\tan ^{-1}(2)$
Solution
$\begin{aligned} & \frac{\mathrm{u}^2 \sin 2 \theta}{\mathrm{g}}=\frac{\mathrm{u}^2 \sin ^2 \theta}{2 \mathrm{~g}} \\ & 4 \sin \theta \cos \theta=\sin ^2 \theta \\ & 4=\tan \theta\end{aligned}$
