Thank you very much for Designing such a great site.
I would be very much obliged if u have time to clear my doubts.
1) U have written that only tangential component of "g" will be considered at the circular path. But do i have to consider centripetal force ?
2)How did u get the time to reach at the end of 1st. circle without knowing the actual radius of the first quarter circle( common to both ball)?
kindly send me the calculation of time to reach at the end of first circle.I mean just before the first ball starts horizontal journey.If u give the total time calculation, then it be very nice.
