If you can squeeze it, the material is not strong enough. Since kinetic energy must be conserved, you can solve for the final velocities because you have two unknowns and two equations (a statement of conservation of momentum and a statement of conservation of energy). For any assignment or question with DETAILED EXPLANATIONS!
