Consider three scenarios for a one-dimensional elastic collision with a stationary target. For each scenario, determine the final velocities of both the projectile mass, v1f, and the target mass, v2f , in terms the projectile’s initial velocity, v0. Assume the masses are sliding on a horizontal surface of negligible friction. Case (a): Both the projectile and target are bowling balls; m1 =m2 =7.25 kg. Case (b): The target is one of the bowling balls, but the projectile is a Styrofoam ball of the same diameter; m1 =140 g, m2 =7.25 kg. Case (c): Now make the Styrofoam ball the target and the bowling ball the projectile; m2 =140 g, m1 =7.25 kg. Compare parts (b) and (c) to the following extremes: (d) when the target is the Earth and the projectile is a tennis ball, and (e) when the target is a frozen pea and the projectile is a truck’s windshield.
