Practice question
Question
In projectile motion, what is true about the total mechanical energy, assuming no air resistance?
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 It remains conserved. Hence option C satisfies projectile formulas.
