A ball of mass m makes a head-on elastic collision with a second ball (at rest) and rebounds with a speed equal to one-fourth its original speed. What is the mass of the second ball?

The mass of the second ball cannot be determined from the information given. The outcome of the collision is only dependent on the masses and velocities of the two objects, and we are given only the mass of one and the velocity of rebound of the other. The information given is not enough to determine the mass of the second ball.
