A particle A is dropped from a height and another particle B is projected in a horizontal direction with a speed of 5 m/sec from the same height. The correct statement is

Asked in NEET 2002 · Projectiles from a height or an incline

Answer: (3) both particles will reach the ground simultaneously

Step-by-step solution

Given: A dropped from rest; B projected horizontally at 5 m/s from the same height.

Idea: the horizontal and vertical motions of a projectile are independent, so the time to fall depends on the vertical motion alone.

Both particles start with zero vertical velocity.

Both fall the same height h under the same g, so both take t=√(2h)/g.

They therefore reach the ground simultaneously, even though B lands further away.

Their landing speeds differ, because B keeps its horizontal 5 m/s.

Why the other options are wrong
