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 2.93MeV . The nuclear radius is 2.75 fm, and you can assume the nucleus remains at rest
With what speed must the proton be fired toward the target?
in (m/s)
Through what potential difference must the proton be accelerated from rest to acquire this speed?
in U = _____V
