⚛️ Physics · Motion in a Plane · NEET & JEE

A stone is projected from ground at angle 37° with 50 m/s. Time to reach max height (sin37°=0.6, g=10):

Answer: 3 s.

A 2 s
B 3 s
C 4 s
D 5 s

Correct answer: B. 3 s

Explanation: Time to max height = u·sinθ/g = 50×0.6/10 = 30/10 = 3 s.

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.
