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. Velocity of A immediately after collision is along unit vector

Answer»

`hati`
`(1)/(2)hati+(SQRT(3))/(2)hatj`
`hatj`
Cant't predict

Solution :Hint : USE impulse-momentum theorem along the rope and conservation of momentum PERPENDICULAR to the rope.
