For items 4 and 5, consider a blue ball A which hits a green ball B of the same mass as shown in the figure. The velocity of the blue ball A just before the collision is vA1 = 20 m/s with the direction as shown. The velocity of the green ball B just before the collision is vB1 = 30 m/s with direction as shown in the figure. The coefficient of restitution between the balls is 0.78. V81 = 30 m/s %3D LOI VA1 = 20 m/s 30°
