Q12. As shown in the image below, ball A and ball B are approaching each other, and
they have a mass of må = 1.7 kg and må ³ 1.3 kg, respectively. The directions of
their initial velocities are shown in the image, and the speeds are VA,1 = 2.7 m/s and
VB,1 = 2.3 m/s. If the coefficient of restitution between the balls is e = 0.5, determine
the velocity of ball B after collision. Right is considered the positive direction and
negative sign must be included if ball B moves to the left after the collision. Please
pay attention: the numbers may change since they are randomized. Your answer
must include 3 places after the decimal point, and proper SI unit.
