The dwnward speed wud be 'u' again....

Take any body thrown vertically upwards with initial vel. u

Final vel. @ topmost height is= 0

Using v= u+at..................................we get t=u/g

In return journey it has 2 cover same dist. again ....so it will take the same time...

Initial vel. =0 Final vel. = x

Solve again......u'll get final vel. as "u"

U can also show it using Moentum Conservation & energy conservation....

Hope it helps...

(rates welcome)....
