1. The velocity of an alpha particle, He2+, with mass m = 6.64x10 2"kg changes from
u1 = (-0.30, 0.45,0.10)c
to
Uz = (-0.50, 0.30, -0.75)c,
where c=3x10%ms1
Determine the change in the particle's kinetic energy. (In the kinetic energy formula, do not forget to
square the speed of light.) Answer: 1.2x10°

2. You place a C film with an unknown thickness in between an Am-241 source and a detector. After one
minute has passed, the detector has registered 10275 counts. You then remove the film, and the detector
registers 11000 counts during a one minute interval. How thick is the C target? Provide an answer in
units of ug/cm2.
