A proton is shot at 5.0x10^7 m/s towards the nucleus of a goldatom. The gold atom has a mass 197 times that of the proton, repelsthe proton and deflects it straight back with 90% of its initialspeed. What is the recoil speed of the gold nucleus?

I understand how to do recoil speed, I'm just unsure of how toincorporate the 90% into the problem. Please explain.
