A projectile is launched at 30° to the horizontal with initial velocity 20 m/s. What is its horizontal range? (g = 10 m/s²)

$R = \frac{u^2 \sin 2\theta}{g}$

A

20 m

B

40 m

C

20√3 m

D

10√3 m

Correct Answer: C — 20√3 m

Explanation:

$R = \frac{u^2 \sin 2\theta}{g} = \frac{20^2 \times \sin 60°}{10} = \frac{400 \times \frac{\sqrt{3}}{2}}{10} = 20\sqrt{3}$ m.
