Question

Two 5 kg balls collide and stick together after the collision. The resultant velocity of the system after collision is 5 m/s. Do we have enough information to determine the energy lost to heat by this system? If not, what is missing?
We need the resultant mass
We need the initial velocities
We need resultant mass and initial velocities
We have enough information

Answer 1

Answer:

No

Explanation:

We need initial velocity and resultant mass of that system
