Moderating a neutron in a nuclear reactor, neutrons released by nuclear fission must be slowed down before they can trigger addi- tional reactions in other nuclei. to see what sort of material is most effective in slowing (or moderating) a neutron, calculate the ratio of a neutron's final kinetic energy to its initial kinetic energy, k/k, for a head-on elastic collision with each of the following stationary tar- get particles. (note: the mass of a neutron is m atomic mass unit, u, is defined as follows: 1 u = 1.66 x 10 kg.) (a) an electron (m 5.49 x 10 u). (b) a proton (m 1.007 u). (c) the nucleus of a lead atom (m 1.009 u, where the 27 207.2 u).

1. explain how you calculate the net force in any direction on the box. 2. suppose an upward force of 15n is added to the box. what will be the net vertical force on the box? 3. what force could be applied to the box to make the net force in the horizontal direction zero? explain. 4. suppose a force of 25n to the right is added to the box. what will be the net force to the right?
