Answer:
Explanation:
According to the law of conservation of linear momentum, the total momentum of both pucks won't be changed regardless of their interaction if no external forces are acting on the system.
Being and
the masses of pucks a and b respectively, the initial momentum of the system is
Since b is initially at rest
After the collision and being and
the respective velocities, the total momentum is
Both momentums are equal, thus
Solving for
The initial kinetic energy can be found as (provided puck b is at rest)
The final kinetic energy is
The change of kinetic energy is
