Homework Statement
A particle A, of mass 3kg, is connected by light, inextensible strings to particles B and C, of masses 5kg and 1kg respectively. They lie at rest on a smooth horizontal plane, with the strings just taut and angle BAC=theta. A then receives and impulse directed away from B and C along the bisector of the angle BAC.Show that A starts to move at an angle alpha to the direction of the impulse, where
tan (alpha) = 2 sin (theta)/6-3cos(theta)
Please provide detailed explanations along with your answer, thanks in advance! :D
