A WIMP of mass m w and velocity Ï < < c scatters elastically from a stationary

Question:

A WIMP of mass mwand velocity Ï… << c scatters elastically from a stationary nucleus of mass mA. Show that the maximum kinetic energy imparted to the nucleus is 

2mлт ,2 v². m, Tmax max (ma + mu )2

For a given mw, what value of mleads to the maximum value of Tmax and what is its value if mw = 60GeV/c2 and Ï… = 220km/s?
