# Suppose you release a body from the top of the tower and project another body vertically upwards at the same time. When and where will the two meet? Could you please show all the steps?

Dear Varun,

when the object reaches maximum height, the velocity of the object is 0 m/s.

It reaches maximum height when the gravity of the body has slowed its velocity to 0 m/s. If there is no gravity I don''t know.

Where there is and you have the objects initial velocity then you can use :

v^2 = u^2+2.a.s

v = Velocity when it reaches Max. height so v = 0
u = Initial Velocity (m/s)
a = Retardation due to gravity, -9.81m/s ^2

And then the unknown (s) is the displacement, or height above ground, and if everything else is in the right format it should be in metres.
