Three billiard balls, the two-ball, the four-ball, and the eight-ball, are arranged on a pool table as shown in the figure below. Given the coordinate system shown and that the mass of each ball is 0.150 kg, determine the gravitational force on the eight-ball due to the other two balls. (Assume a = 1.2 m and b = 2.4 m. Express your answer in vector form.)

    Two billiard balls, a cue ball and an eight ball, of equal mass undergo a perfectly elastic head-on collision. If the cue ball’s initial speed was 8.8 m/s, and the eight ball's was 8.3 m/s in the opposite direction, what will be the velocity of the eight ball after the collision? Consider the initial direction of the cue ball to be the positive direction.

    2- Two identical billiard balls may move freely on a horizontal table. Ball A has a velocity of 0.4 m/s as shown, and hits ball B, which is at rest, at point C defined by ? = 40° (the line of impact is along 40° path with respect to the horizontal direction). Assuming no friction, and knowing the coefficient of restitution between the two balls is 0.75, determine the velocity of each ball after impact.
