6. Two particles, each of mass m, are connected by a light inextensible string of length 2l. Initially they lie on a smooth horizontal table at points A and B distant l apart. The particle at A is projected across the table with velocity u. Find the speed with which the second particle begins to move if the directions of u is.
(a) along AB,
mu = (m+m)v
v = u/2
But the given answer is u/2 and mu/2. Can anyone explain to me why there are 2 answers? Thanks.
