I spent about over an hr for this problem and still cant figure it out.


expressing the kinetic energy in terms of momentum (k= 1/2^2mv=p^2/2m) prove using symbols not numbers that the fractional loss during the collision is equal to M/(m+M).

This can't be the whole of the problem. What collision?
