AP Physics B - Momentum

1

Two astronauts, Ann and Bob, conduct a collision experiment in a weightless, frictionless environment. Initially Ann moves to the right with a momentum of $p_{Ai}=30 \frac{kg*m}{s}$ , and Bob is initially at rest. In the collision, the two astronauts push on each other so that Ann's final momentum is $p_{Af}=-5\frac{kg*m}{s}$ to the left. What is Bob's final momentum?

Ball A, traveling $7\frac{m}{s}$ to the right, collides with ball B, traveling $8\frac{m}{s}$ to the left. If ball A is 4kg and ball B is 6kg, what will be the final velocity and direction after a perfectly inelastic collision?
