Physics - Center of Mass Question with Solution | TestHub

A small ball of mass m is placed on a super ball of mass M & the two balls are dropped from height H (H is very large compared to radius of balls). How high (in m) does small ball rise after collision? All collisions are head on elastic &$(\mathrm{m}\ll \mathrm{M}).\left(\mathrm{H}=1\mathrm{m}\&\mathrm{g}=10\mathrm{m}/{\mathrm{s}}^2\right)$
