Compute the final velocities v1' and v2' after the collision of the two cylinders which slide on the smooth horizontal shaft. The velocities are positive if to the right, negative if to the left. The coefficient of restitution is e = 0.70.Before collision, cylinder 1 of mass m1 = 3.2 kg is sliding from left to right and cylinder 2 of mass m2 = 1.5 kg is sliding from right to left with velocities v1 = 7.8 m/s, v2 = 6.6 m/s, respectively.
