Question

In a 1D collision of identical particles A and B, B is initially at rest and A has momentum p. During impact B gives impulse J to A. Which statements are correct?

G1 Physics · Accepted Answer

Use conservation of linear momentum together with e = (relative speed of separation)/(relative speed of approach). Solving the two collision equations gives B: During impact A gives impulse J to B.; C: Coefficient of restitution is J/p - 1..
