Wow... where do you even start?
You have been able to get a part time job with a medical physics group investigating ways to treat inoperable brain cancer. One form of cancer therapy being studied uses slow neutrons to knock a particle (either a neutron or a proton) out of the nucleus of the atoms which make up cancer cells. The neutron knocks out the particle it collides with in an inelastic collision. The heavy nucleus essentially does not move in the collision. After a single proton or neutron is knocked out of the nucleus, the nucleus decays, killing the cancer cell. To test this idea, your research group decides to measure the change of internal energy of a nitrogen nucleus after a neutron collides with one of the neutrons in its nucleus and knocks it out. In the experiment, one neutron goes into the nucleus with a speed of 2.0 x 10^7 m/s and you detect two neutrons coming out at angles of 30o and 15o. You can now calculate the change of internal energy of the nucleus.
Some information I think might come in handy:
mass of a neutron is 1.68x10^-27 kg
Where can I even begin this?

What in the heck should I do with a bunch of inherited medical machines?
My uncle was a medical researcher specializing in new cancer therapies.
He died recently, and I was willed the contents of his basement, which turned out to contain a variety of medical devices of various sorts, among them:
-A Siemens Primus K dual energy linear accelerator for radiotherapy
-A Varian 730-ES ICP-OES system
-A Siemens Magnetom Espree 1.5T open bore MRI machine
-A Hologic QDR 1000 bone densitometer (whole body)
-The ASSEMBLY of a gamma knife system, but not the patient table or even a model number - I assume this was one of my uncle's projects, and is probably modified from the original
What should I do with this stuff? Particularly the gamma knife, which presumably has cobalt-60 in it. Can I sell it? Should I contact a university? Should I save any of this in case I get cancer one day and need to treat myself? (I'd do some reading before trying to operate these machines, mind you).
If I sold these devices, how much could I make?

Is 25 to old to try and be a radiology doctor?
I finished highschool, with not so great grades. I felt that I wasn't ready to go to college because I had no goal or dream at the time...
However, I wish to be radiology doctor (cancer therapy) someday...
I just want to know if my age is an issue now? And how hard will it be? I need realistic answers too. :)
Thank you in advance.
