The two disks A and B have a mass of 4 kg and 5 kg respectively. They collide with the initial velocities shown. The coefficient of restitution is e = 0.75. Suppose that (VA) = 6 m/s. (V8) =7 m/s. (Figure 1) Figure (VB)1) (VA)I 60 Line of impact Part A. Determine the magnitude of the velocity of A just after impact. Part B Determine the angle between the x axis and the velocity of A just after impact measured clockwise from the negative x axis. Part C Determine the magnitude of the velocity of B just after impact. Part D Determine the angle between the x axis and the velocity of B just after impact measured clockwise from the negative x axis.
