Question

A body is thrown vertically upward with velocity u. If the acceleration during this upward journey is g, then the greatest height h to which it will rise is,​

Answer 1

Answer:

Explanation:

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

Answer 2

Explanation:

ANSWER

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, v2=u2+2as

we have 0=u2−2gh. (taking g in the upward direction)

or h=u2/2g
