Question

A projectile is launched at 42m/s at 30∘. What is its range? (Take g\=9.8m/s2,sin⁡60∘\=0.866)

Options

Choose one · Correct answer highlighted

Explanation

Projectile motion splits into horizontal uniform and vertical accelerated motion per NCERT Chapter 4. Range R=u²sin2θ/g and max height H=u²sin²θ/2g. Using given u, θ, g, calculation yields 100 m. Hence option A satisfies projectile formulas.
