Comparing Two Projectiles

Two projectiles of same mass and with same velocity are thrown at an angle 60o and 30o with the horizontal, then which will remain same

Show answer and solution

Answer: (b)

  1. 60∘60^\circ and 30∘30^\circ are complementary: sin⁡120∘=sin⁡60∘\sin 120^\circ = \sin 60^\circ, so the range is the same.
  2. T∝sin⁡θT \propto \sin\theta and H∝sin⁡2θH \propto \sin^2\theta differ for the two angles.
  3. So the answer is (b) range of projectile.
