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.

A hydrogen nucleus has a radius of 1.1 x 10-15 m and the electronis about 5.5 x 10-11 m from the nucleus. Assume the hydrogen atomis a ball with a radius of about 5.5 x 10-11 m and the nucleus is aball with a radius of 1.1 x 10-15 m.

(a) What is the volume of the atom?
(b) What is the volume of the nucleus?
(c) What percentage of the atom is occupied by the nucleus?
d) How much work (in electron volts) must be performed by anexternal force to bring in another proton (from very far away) tothe "surface" of the nucleus? (Ignore the effects of the electron.)

Most of the Sun’s energy comes from the proton-proton chain inwhich four hydrogen nuclei (i.e., protons)
fuse into one helium nucleus.
(a) Calculate how much mass is “lost” in one proton-proton chainreaction.
(b) How much energy is produced in one proton-proton chainreaction? In other words, find a change in
the rest mass energy before and after the reaction.
(c) The total power output of the Sun is 3.85×1026W. Ifall of it comes from the proton-proton chains,
how many kilograms of mass is being converted into energy in theSun in one second?
