Ball 1 has an inertia of 0.500 kg and ball 2 has an inertia of 0.600 kg . Ball 1 is moving away from you at 5.0 m/s, and you decide to throw ball 2 at it to make it go faster. The balls collide head-on, and the coefficient of restitution for the collision is 0.83. A- How fast must ball 2 be traveling in order to double the velocity of ball 1? Express your answer with the appropriate units. B- What is the initial relative velocity of the two balls? Express your answer with the appropriate units. C- What is their reduced inertia? Express your answer with the appropriate units. D-What percentage of the original kinetic energy is convertible? E-What are the final velocities of the two balls immediately after the collision? Enter your answers numerically separated by a comma.

Ball Collision. A ball with a mass of 0.600 kg is initially at rest. It is struck by a second ball having a mass of 0.400 kg, initially moving with a velocity of 0.250 m/s toward the right along the x-axis. After the collision, the 0.400 kg ball has a velocity of 0.200 m/s at an angle of 36.9° above the x axis in the first quadrant. Both balls move on a frictionless, horizontal surface. Find the magnitude of the...
