Question
Question 4) As shown in the figure, three spheres of mA = 1kg, mB = 2kg and mC = 4kg slide towards point O in a frictionless environment. The velocities of spheres A and B are shown in the figure. These three spheres arrive at point O at the same time. If these three spheres move together at a speed of 1m / s in the + x direction after the collision; a) What should be the magnitude of the initial velocity of mass C? b) What angle should the mass C make with the x-axis? c) If the velocity of the mass C is as in a), what will be the change in the kinetic energy of the system consisting of these three spheres as a result of the collision?
