Objects A and B undergo a one-dimensional elastic collision. The initial speed of A is vAi and the initial speed of B is zero. Equations (8.24) and (8.25) give the final velocity components of the objects after the collision. Let mA = amB, where a is a constant. (a) What is the value of a if the final kinetic energy of B equals the initial kinetic energy of A? (b) What is a if the final kinetic energies of A and B are equal?

Question

Objects A and B undergo a one-dimensional elastic collision.
The initial speed of A is vAi and the initial speed of B is zero. Equations
(8.24) and (8.25) give the final velocity components of the objects after
the collision. Let mA = amB, where a is a constant. (a) What is the
value of a if the final kinetic energy of B equals the initial kinetic energy
of A? (b) What is a if the final kinetic energies of A and B are
equal?
