Two particles A and B of masses M and m respectively are connected by an inelastic string which passes over a smooth pulley. Initially A is at rest on a smooth horizontal table and B hangs at a height h above the table. B is then raised through an extra height H and allowed to fall.

i. Show that if (m

^{2}/(M

^{2}-m

^{2}))H<h, B does not reach the table.

ii. If (m

^{2}/(M

^{2}-m

^{2}))H≥h show that, during the motion, A rises to a maximum height m{2(M+m)h+mH}/(m+M)

can anyone explain how the motion happens and what is the condition i need start to prove the above questions

thanks...
