Question

Q) A body is thrown vertically upward with velocity (u), the greatest height to which it will rise is,

a) $u/g$
b) $u^{2}/2g$
c) $u^{2}/g$
d) $u/2g$

Answer 1

Answer:

option b ) u^2 / 2g

hope it helps

Answer 2

Explanation:

The body that is thrown vertically upward with velocity u will have final velocity v=0 at the greatest height h.

The body that is thrown vertically upward with velocity u will have final velocity v=0 at the greatest height h.Substituting the given values in the third equation of motion, v^2= u^2+2as

The body that is thrown vertically upward with velocity u will have final velocity v=0 at the greatest height h.Substituting the given values in the third equation of motion, v^2= u^2+2aswe have 0 =u^2 −2gh. (taking g in the upward direction)

The body that is thrown vertically upward with velocity u will have final velocity v=0 at the greatest height h.Substituting the given values in the third equation of motion, v^2= u^2+2aswe have 0 =u^2 −2gh. (taking g in the upward direction) or h=u^2/2g
