In a one dimensional collision between two identical particles A and B, B is stationary and A has momentum p before impact. During impact, B gives an impulse J to A. Then, coefficient of restitution
between the two is

Question

Infinity Learn · Accepted Answer

Let uA and uB be the velocities of A and B respectively before impact and vA and vB be the velocities of A and B after impact.Before impact, uB $$=$$ $$0$$                        p $$=$$ muAAfter impact, $$p-J$$ $$=$$ mvA and J $$=$$ mvBCoefficient of restitution, e $$=vB-vAuA-uB=J-(p-J)p$$                                            $$=2J-pp=2Jp-1$$
