Question

A body is thrown vertically upward with velocity (u). The greatest height h to which

it will rise is

a)u/g b) u2/2g c) u2/g d) u/2g​

Answer 1

Answer:

ans is u²/2g

Explanation:

initial velocity = u m/s

final velocity = 0 m/s

acceleration = g m/s² ( here will be taken negative because it acts downwards )

height = h m

by 3rd equation

v²-u²= 2gs

0-u² = 2(-g)s

-u²= -2gs.

s = u²/2g
