As per your syllabus, eqn 3.40b, the time of flight T_f of a projectile (returning to launch level) is which?
Av₀ sin θ₀ / g
Bv₀ / g
C2 v₀ sin θ₀ / g
Dv₀² sin 2θ₀ / g
Answer & Solution
Correct answer: C. 2 v₀ sin θ₀ / g
syllabus eqn 3.40b: T_f = 2 t_m = 2 v₀ sin θ₀ / g.
Symmetric about apex of parabola.
