Question

A body is thrown vertically upward with a velocity u. Find the expression of

greatest height and total time taken for the entire journey.​

Answer 1

Answer:

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=2gu2.

Answer 2

A body is thrown vertically upward with velocity u, the greatest height h up to which it will rise is h=u22g. A.
