Q. Suppose you have a large crate you wish to lift off the floor. To accomplish this you have been given a pulley and some rope. The crates has a hook on it, as does the ceiling. Describe two ways in which you could you this equipment to raise the crate. Accompany each description with a diagram showing how would you would set it up.

Q. an alpha particle with kinetic energy 13.0 MeV makes a head on collision with a gold nucleus at rest. what is the distance of closest approach of the two particles? (Assume that the gold nucleus remains stationary and that it may be treated as a point charge. The atomic number of gold is 79, and an alpha particle is a helium nucleus consisting of two protons and two neutrons.)
