Two tennis balls undergo a head-on elastic collision. Under which of these initial conditions is it impossible for both balls to be moving in the same direction after the collision? (a) the lighter ball is stationary and the heavier ball is in motion. (b) the two balls have the same mass and are initially moving in the same direction, and they collide because the faster-moving ball overtakes the slower-moving one. (c) the two balls have the same mass and only...

Two particles, of mass m and mass nm, undergo a head-on, fully elastic collision. (Here n is just a unitless number.) Before colliding the particles approach one another with equal speed v. Snapshots of the particles before, during, and after the collision are shown above. After the collision the first particle moves away with speed 2.95v in the exact opposite direction, and the velocity of the second particle is unknown. What is the value of n? Before Collision (m)-><-(nm) Collision...
