mass A = 100kg
mass B = 1000kg
initial speed of mass A = 40m/s

That would violate both conservation of momentum and conservation of energy.

Paul, you say you know what magnitude means and you say you know what momentum means, but you don't. Please please look up "momentum" on google instead of repeating the same mistakes over and over again.
