Answer:
15.0 m/s
Explanation:
When elastic collision occurs, the final velocities, v of the bodies are obtained by
Where u and m denote initial velocities and mass while the subscripts 1 and 2 are for tennis ball and the other ball
Substituting 0.311 for mass of tennis, 0.0570 for mass of the other ball, 30.3 m/s for velocity of tennis ball and -19.2 m/s
