Homework Answers
It can be lost as mechanical energy, where the energy causes deformation of the system, and hence results into the change of shape of the two bodies.
This loss can also appear in the form of sound energy where you might hear a loud thud, which occurs whenever two material collide.
Other examples in which form it can happen is heat energy, where the systems colliding with each other might cause some increase in temperature, or light energy, where you might be able to see some sparks when they happen. Although heat and light energy can be interdependent on each other.

7. About kinetic energy loss during collision processes, answer the following questions: (a) If the collision is perfectly inelastic, is all the kinetic energy lost? (Question 19 of chapter 9.) (3 points) (b) For 1D inelastic collisions (not necessarily perfectly inelastic), apply Eq. (⋆) to find the maxi- mal kinetic energy loss during the collision process. Hint: Use the fact that the velocity must be real. (c) Does the maximal kinetic energy loss correspond to perfectly inelastic collisions?

If the alpha particles have an initial kinetic energy of 7.7 MeV, then assuming a head-collision between an alpha particle (helium nucleus with +2e charge) and a gold nucleus (79 protons, so +79e charge), and using conservation of energy at the point of closest approach when all of the alpha particle's kinetic energy is converted to electric potential energy, calculate the approximate distance of closest approach (and thus coarsely estimate the size of the nucleus)
