During a game of marbles, the “shooter,” a marble with three times the mass of the other marbles, has a speed of 3.2 m/s just before it hits one of the marbles. The other marble bounces off the shooter in an elastic collision at an angle of 40°, as shown, and the shooter moves off at an angleθ. Determine (a) the speed of the shooter after the collision, (b) the speed of the marble after the collision, and (c) the angleθ.
