Two billiard balls of identical masses collide. The red ball was traveling at a velocity of 7 m/sec. The black ball at a velocity of 12 m/sec. If the black ball after impact had a velocity of 5 m/sec, what was the velocity of the red ball after collision? This was all that was given to me. I guessing they are colliding to each other.

    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.

    A billiard ball is shot east at 2.80 m/s. A second, identical billiard ball is shot west at 1.20 m/s. The balls has a glancing collision, not a head-on-collision, deflecting the second ball by 90° and sending it north at 1.60 m/s. What is the angle that the velocity of the first ball makes after the collision, with respect to the east direction?

    two balls that are set to be collide elastically, give these two balls specific masses and initial velocity. The balls cannot have the same mass, and they must be moving in both the x- and y-directions. These are the data: Mass for ball 1=3kg Mass for ball 2=5kg Initial velocity ball 1=1.50 Initial velocity ball 2=2.0 Use Conservation of Momentum in x and y, as well as Conservation of Energy, to determine the final velocities of the balls after the...
