Two objects collide inelastically. We've already seen examples where some of the mechanical energy (kinetic, gravitational and spring potential) is converted to other forms of energy (heat, sound, crumpling, etc). Can all of the initial mechanical energy be converted into other forms of energy during the collision?
A. Yes, but only for certain special initial conditions.
B. Yes, provided that the objects are soft enough.
C. No, this violates a fundamental law of physics.
D. None of the above.
