Per NCERT §3.9 eqn 3.39, the trajectory equation of a projectile y = (tan θ₀)x − [g/(2v₀²cos²θ₀)]x² describes which curve?
AStraight line
BCircle
CHyperbola
DParabola
Answer & Solution
Correct answer: D. Parabola
NCERT §3.9 eqn 3.39: y = ax + bx² is a parabola. Path of a projectile under uniform gravity (no air drag) is parabolic.
