Please answer the question in a step by step process with the correct answer

An object of mass m1 : 8.01kg travels at 51,- : 11.68%; 7 6.31 g; while a second object of mass m2 : 5.85kg travels at 172,- : 75.81%; + 9.16%} in otherwise empty space. The two objects collide. After the collision m2 travels with a velocity 62f : 6.35%1' + 3.94%3' (The input below will only mark answers correct if they vary by no more than 1% from the correct value.) What the total momentum of the two object after the collision? Ema = kg%2'+ kg%2
