okay thank you...I figured it out ..I just equalized the two distance !

okay...then what to do?..Please help me out !..Should I equalise their distance travelled??..Will that be helpful?

yess...very sorry...It was my fault..I kept having a delusion that it was thrown upwards

Well yes...sorry It was my fault...indeed the second was thrown downwards too... And I think I can calculate the distance they have traveled and also their final velocities !

But how to solve after that??..please help!

welll...as far as I understood...the first ball was thrown vertically downwards and the second vertically upwards...and coming to your question the first ball would have stayed 4 sec in flight before the second one hits it...I guess :)

So the question which is troubling me is as follows: A ball is thrown vertically down with velocity of 5 m/s.With what velocity should another ball be thrown down after 2 seconds so that it can hit the 1st ball in next 2 seconds. I couldn't ses the way out..as I feel the height of the 1st ball...

:smile:Thanks perfectly clear to me now !

Can you please elaborate it ?? Thanks btw! :smile:

Light from the sun takes about 8 mins to reach the earth. But does the time get delayed appreciably due to Earth's atmosphere?? Thanks in advance !

And please teach me how to give such prominent integral sign like the ones you are typing !?

Is it okay for me to learn triple integral now?? And if yes then where to start??

But what is that /iiint dV and how to solve it ??

Thanks :smile:

yeah maybe ∫pi*(r^2-x^2)dx with integral limits from -r to r ??
