Twin A m/s

Twin B m/s

**Steve**, Friday, October 19, 2012 at 5:25pmmomentum of A and P (pack) is conserved, so

v*59.6 + 3*12 = 0

v = -.60 m/s for twin A

after catching the pack, momentum of P and B is conserved, so

3*12 = v(12+59.6)

v = .50 m/s for B+pack

-.6*59.6 + .5*71.6 =~ 0 as expected
