FIGURE Q25.2 shows the potential energy of a proton (q = +e)
and a lead nucleus (q = +82e). The horizontal scale is in units of
femtometers, where 1 fm = 10-15 m.

How much initial kinetic energy does the proton need to
reach a turning point 10 fm from the nucleus? Explain.
b. How much kinetic energy does the proton of part a have when
it is 20 fm from the nucleus and moving toward it, before the
collision?
