Answer:
a) 0.9995c
b) 5641MeV
c) 91670 MeV
Explanation:
(a) The speed of approach is given by the formula:

(b) the kinetic energy is given by:
![E_k=m_0c^2[\frac{1}{\sqrt{1-\frac{v^2}{c^2}}}-1]](https://tex.z-dn.net/?f=E_k%3Dm_0c%5E2%5B%5Cfrac%7B1%7D%7B%5Csqrt%7B1-%5Cfrac%7Bv%5E2%7D%7Bc%5E2%7D%7D%7D-1%5D)
by replacing c=3*10^8m/s, m_0=1.67*10^{-27}kg we obtain:

(c) in the rest frame of the other proton we have:
![E_k=m_0c^2[\frac{1}{\sqrt{1-\frac{u^2}{c^2}}}-1]](https://tex.z-dn.net/?f=E_k%3Dm_0c%5E2%5B%5Cfrac%7B1%7D%7B%5Csqrt%7B1-%5Cfrac%7Bu%5E2%7D%7Bc%5E2%7D%7D%7D-1%5D)
by replacing we get

hope this helps!!
