Physics CIE help
tmisterr:
thanks a alot for your help with number 9 and 15!! but for number 11, why do you assume that the balls are of the same mass? and isn't it that kinetic energy is conserved not that momentum is equal for both bodies? in ur cause if A and B are of the same mass this means that vA and vB are equal so that they have equal momentum.
How bout if you use relative speed of approach is equal to relative of recoil?? this is how im doing it but getting a different answer
