A ball of mass in m= 1 kg is hung vertically by a thread of length l = 1.50 m . Upper end of the thread is attached to the ceiling of a trolley of mass M= 4 kg . Initially, the trolley is stationary and it is free to move along horizontal rails without friction. A shell of mass m=1 kg, moving horizontally with velocity v_(0) = 6 m//s collides with the ball and gets stuck with it. As a result, the thread starts to deflect towards right. The velocity of the combined body just after collision is
