2a. In case 1), we take one proton as the target and set it to rest. We accelerate the other proton to 100 GeV (total energy) and let it hit the proton at rest. Compute the s in this situation. b. In case 2), we use a collider system to accelerate both protons to 100 GeV (total energy) and let them move against each other and get collision. It means P1 = - P2. Compute again the s in this situation.
Hint: you may use the following formula during your calculation:
• the proton mass of m_p c^2 = 1 GeV
• for each proton, E^2 = (m_p c^2)^2 + (Pc)^2 with E the total energy of the proton and P its momentum.

3. Can a cyclotron be used to accelerate an electron to 100 MeV? How about accelerate a Proton to
100 MeV? Give your reason for your results.

Please serious answers only, I will flag you if you say you don't know and just want points. I really need the help and this is due tonight and my instructor didn't provide any help nor did my classmates.
