3. Consider the following data for two balls involved in an elastic collision: Ball 1 Ball 2 m = 28 g m =16 g v = 0.5 m/s (to the right) v = 0.3 m/s (to the right) Determine: a. Final velocities of the balls if they stick together during collision b- Initial and final momenta of the balls k c. Initial and final kinetic energies of the balls
