Three spheres, each of mass m, can slide freely on a frictionless, horizontal surface. Spheres A and Bareattached to an inextensible, inelastic cord of length "l" and are at rest in the position shown where sphere B is struck by sphere C which is moving to the right with a velocity v_(0). Knowing that the cord is taut where sphere B is struck by sphere C and assuming "Head on" inelasticimpact between B and C, we can 't conservekinetic energy of entire system. If velocity of C immediately after collision becomes (v_(0))/(2) in the initial direction of motion, the impulse due to string on sphere A is |
