You didn't supply enough information to solve this problem. Two formulae are important to solve problems with momentum: (1) the definition of momentum: momentum = mass x velocity. (2) the total momentum (sum of individual momenta) before and after the collision must be the same.
It can change, but it's always equal to (mass of the ball) times (speed of the ball).
Momentum is mass times velocity. But in this case, you don't even need to calculate that: If I understand correctly, the balls have the same mass, the same speed, and they move exactly in opposite directions - so any momentum from one ball is exactly offset by the momentum of the other ball. In other words, if one ball has a momentum of +M, the other one will have a momentum of -M.
The resultant momentum of the two objects will roughly equal that of the dynamic object in magnitude and direction, minus some energy lost due to friction during the collision. Think of what happens when a cue ball hits a stationary ball in pool.
When the 0.500kg ball collides with the stationary ball, momentum is conserved. Meaning, initial momentum = final momentum. Momentum of an object is = mass(m) x velocity (v). If two objects are in the system, then you have to add up both initial momentums and set them equal to the final momentums... So... m x v(initial, first object) + m x v(initial, second object) = final momentum. (0.500kg)(4.0m/s) + (1.0kg)(0m/s) = final momentum. So the final momentum equals 2.0kgm/s... D. 2.0 kgm/s
A baseball flies through an open window and collides with a vase. The momentum of the ball and vase after the collision is the same as the momentum of the ball alone before the collision.
By the Law of Conservation of Momentum, the total momentum after the collision must be the same as the total momentum before the collision.
yes
inertia
The total momentum of the two balls.
The total momentum before the collision is the same as the total momentum after the collision. This is known as "conservation of momentum".

No. The thing that is the same before and after the collision is the total momentum.
It is equivalent to the change in momentum of the ball.
Consevation of momentum applies. The final compond mass must have the same momentum as the net momentum of the two balls before the collision. Remember, momentum is a vector and direction is important. For example if the two balls are moving toward each other with the same momentum, the net momentum is zero because they are moving in opposite directions. So the compound ball will not move. Or, if ball 1 is moving left and has a greater momentum then ball 2 ,moving right, then the compound ball will move left. Its momentum will equal the difference between the two momentums because when you add two vectors in opposite directions you subtract their magnitudes. Mechanical energy (potential + kinetic) is not conserved in this collision because some mechanical energy is lost as heat in the collision.
If you're suggesting something like an auto accident, the energy of the collision is used to deform materials in the structural elements of the vehicle(s). It also heats them. The primary design features of cars includes a lot of thought to where the energy of a collision can go. Bumpers collapse, body panels and their strengthening members fold and become compressed, and a top or roof can collapse down. All this sinks ("sucks up") energy. And if it all works in an optimal way, you can climb out and walk away.
It can change, but it's always equal to (mass of the ball) times (speed of the ball).
