Question

9. Three particles A, B and C, each of mass m, are at rest on a smooth horizontal table at the vertices of an triangle of side 2a. The particle A is connected to particles B and C by light inextensible strings each of length 2a. The particle A is given of the table and in a direction perpendicular to the line joining B and C, so that both strings receive an Find equilateral impulse of magnitude mu, in the plane an impulse. (a) the impulse in the string joining A and B, (b) the initial speed of A At a later time, B and C collide. For the instant immediately before this collision, find (c) the speed of A (d) the velocity of B relative to C
