There particles A, B and C have masses m, 2m and m respectively. They lie on a smooth horizontal table connected by light inextensible strings AB and BC. The string are taut and lt ABC = 120^(@) . An impulse is applied to particle A along BA so that it acquires a velocity u. Find the initial speeds of B and C.
