Question

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

Answer 1

Hey there !!!!

________________________________________________________

If a body is thrown vertically upwards with initial velocity "u" 

Maximum Height of body =u²/2g

As  2gh=v²-u²

At maximum height final velocity of body is zero. ⇒⇒⇒v=0

So, 2gh=v²-u²
 
          2gh=-u²

           h=-u²/2g

Distance can't be negative so,

       h=u²/2g
