A projectile reaches a maximum height of 30 m and lands 60 m from the launch point. The tangent of its angle of projection is:

Answer: 2.

A 1
B 2
C 4
D 0.5

Correct answer: B. 2

Explanation: tanθ = 4H/R = 4 × 30/60 = 2.

Projectile trajectories launched at 15, 30, 45, 60, 75 and 90 degrees at the same speed, each annotated with range R, maximum height H and time of flight T, with coloured dots marking equal time intervals

Projectiles at equal speed: range is maximum at 45°, and complementary angles (30° and 60°) share the same range. Image: Cmglee, CC BY-SA 3.0, via Wikimedia Commons.

Concept context

Vectors, projectile motion, uniform circular motion, and relative velocity - the foundation of 2D kinematics for NEET and JEE.
