Question

Two stones are projected from the top of a cliff $h$ metres high, with the same speed $u$ , so as to hit the ground at the same spot. If one of the stones is projected at an angle $θ$ to the horizontal then the $θ$ equals

Options:

Answer:

A

Solution:

$R = u \frac{2 h}{g} = (u cos θ) \times t$ $t = \frac{1}{c o s θ} \frac{2 h}{g}$
