NAME: __________________________________________ Quiz #9b: Phys270 1. [ 10 pts] To initiate a nuclear reaction, an experimental nuclear physicist wants to shoot a proton into a 12 C nucleus. The proton must impact the nucleus with a kinetic energy of 3.00 MeV. The nuclear radius is 3.00 fm. You can assume the nucleus remains at rest and the proton’s velocity is non-relativistic. [Note: 1 eV = 1.6 x 10 ‐19 J] a. [5 pts] With what speed must the proton be fired toward the target?
