Practice question
Question
In projectile motion, what is the angle between the velocity and acceleration vectors at the highest point?
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 90°. Hence option C satisfies projectile formulas.
