Answer:
D) 50%
Explanation:
According to conservation of momentum:

Assuming that the second taffy started at rest, both pieces have the same mass and that they combined after the collision, their final velocity is:

The initial kinetic energy of the system is:

Since the second taffy was not moving, it had no kinetic energy at first.
The initial kinetic energy of the system is:

The percentage of kinetic energy that becomes heat is given by:

THerefore, 50% of the kinetic energy becomes heat
