Two coins A and B have the initial velocities shown just before they collide at point O. If they have weights of W_{A} = 13.2(10^{-3}) lb and W_{B} = 6.6(10^{-3}) lb and the surface upon which they slide is smooth, determine their speed just after impact. The coefficient of restitution is e = 0.65.

[A].

v_{A2} = 1.856 ft/s, v_{B2} = 3.18 ft/s

[B].

v_{A2} = 1.871 ft/s, v_{B2} = 2.76 ft/s

[C].

v_{A2} = 1.772 ft/s, v_{B2} = 2.88 ft/s

[D].

v_{A2} = 1.755 ft/s, v_{B2} = 2.92 ft/s
