Question

A body is thrown vertically upward with velocity u, the greatest height h to which it will
rise is.
(a) w/g (b) 1/2g (c)ừ g (d) u/2g​

Answer 1

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

option ( b) is correct .
