Question

A body is thrown vertically upward with the 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

HEY..
FRIEND...

HERE YOUR ANSWER
............................................................

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 .
