Question

A body is thrown vertically upward with velocity u, the greatest height h to which it will
rise is,
(a) ug (b) 1/28 (c) w/g (d)u2g​

Answer 1

Refer to the attachment........

answer is

$= \frac{u {}^{2} }{2g}$

Answer 2

A body is thrown vertically upward .

at maximum height velocity of body = 0

use kinematics formula ,

v² = u² + 2as

here v = 0

a = -g

s = H

0 = u² -2gH

H = u²/2g

hence, maximum height attained by body u²/2g
