a 0.275-kg ball makes an elastic head-on collision with a second ball initially at rest. the second ball moves off with half the original speed of the first ball. (a) What is the mass of thesecond ball? (b) What fraction of the original kinetic energy(change in KE/KE) getstransferred to the second ball?
The only part i need someone to do is B. Can someone please explain in full detail not just copy it off another website. and show all steps, not just the eqaution i use, thanks
