A projectile is launched at 40m/s at 45∘ from a height of 10m. What is its range? (Take g\=10m/s2,sin45∘\=0.707)
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 150 m. Hence option A satisfies projectile formulas.
