Answer:
The total kinetic energy of the system before the collision is 57 Joules.
Explanation:
Given that,
Mass of first block,
Speed of first block,
Mass of second block,
Speed of first block,
We need to find the total kinetic energy of the system before the collision. It is equal to the kinetic energies of both the blocks. It is given by :
So, the total kinetic energy of the system before the collision is 57 Joules.
