At what angle $θ$ to the horizontal should an object is projected so that the maximum height reached is equal to the horizontal range?

Answer:

Solution:

Given, $H = R$

or $\frac{u^{2} \sin^{2} θ}{2 g} = \frac{u^{2} \sin 2 θ}{g}$

$\frac{\sin (θ) \times \sin (θ)}{2} = 2 \sin (θ) \times \cos (θ)$

$\Rightarrow \tan θ = 4$

$\Rightarrow θ = \tan^{- 1} (4)$
