⚛️ Physics · Motion in a Plane · NEET & JEE

Two cars start from rest at same point and move in same direction. Car A accelerates at 4 m/s² and Car B at 2 m/s². After 10 s, separation between them is:

Answer: 100 m.

A 100 m
B 200 m
C 300 m
D 400 m

Correct answer: A. 100 m

Explanation: sA=½×4×100=200 m. sB=½×2×100=100 m. Separation=100 m.

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.
