a 150 kg football player has a momentum of 750kg m/s and he tackles another player with a mass of 100 kg and a velocoty of 0m/s.

momentum will be zero since it asks for the intial momentum and the second player has a velocity of zero. the formula for momentum is mass times velocity, so 100kg x 0m/s = 0.

You need to make an assumption here. I am assuming that a tackle means that the 150-kg guy grabs the 100-kg guy and they are stuck together for a short time until they probably both fall to the ground.
So, the total momentum immediately after the tackle is 750 kg m/s, and that applies to a mass of 250 kg.
That means the speed of the two guys together is 3 m/s.
That means the momentum of the 100-kg guy is 300 kg m/s
