total momentum in the system is constant
momentum gained/lost by one object is lost/gained by the other object
Before colliding the momentum Of Block A is +450 kg • m/s and Block B is -150 kg • m/s After Block A has a momentum +100 kg•m/s What is the momentum of Block B afterwards?
Please help quickly

Momentum before = Momentum after,
M1*V1 + M2*V2 = M1*V3 + M2*V4,
450 - 150 = 100 + M2^V4,
M2*V4 = 200 kg*m/s = Momentum of Block #2(Blk. B).
M1*V1 + M2*V2 = M1*V3 + M2*V4,
450 - 150 = 100 + M2^V4,
M2*V4 = 200 kg*m/s = Momentum of Block #2(Blk. B).
