The formulas for elastic collisions are: v1 = u1(m1-m2)/(m1+m2) v2 = 2m1u1/(m1+m2) v1 = 5(5-6)/(6+5) = -5/11 m/s = -.45 m/s v2 = (2*5*5)/(5+6) = 50/11 m/s = 4.5 m/s So you got the right answers if you add a negative sign to v1 since it bounces backwards after the collision.

Take the first several derivatives to help find a pattern. This is what I found: the nth derivative is [((-1)^n)(n!)]/[(x+2)^(n+1)
