Question

MCQ: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

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 .

Answer 2

Answer:

option b is correct.

Explanation:

v=0

a=-g

s=h

v^2= u^2 + 2as

0 = u^2 - 2gh

H = u^2/2g
