Question

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

• A. Time of flight
• B. Horizontal range of projectile
• C. Max height acquired
• D. All of them

Answer 1

Answer: (B)

Horizontal range of projectile

Answer 2

$R = \frac {2υ^2sin\ θ\ cos\ θ}{g}$

Range of a projectile for angles of projection θ and 90–θ are same.

So, the correct option is (B): Horizontal range of projectile
