Evaluate the answer of all part of the given question
Question- Now suppose the gliders in the previous problem collide completely inelastically so that they stick together rather than rebounding off each other after they collide. Their masses and initial velocities are the same as in that problem.
Part A-
Find their common final velocity.
Part B- Compare the initial and final kinetic energies.
I need help to to solve all part of the above question.
