What is the total momentum between two identical balls traveling toward each other at the same speed from opposite directions?

They have identical momentum before the collision . The total momentum will the the same before and after the collision. When the balls collide they will bounce apart both with same force and so the same momentum as originally - but in opposite directions. This assumes no energy loss in an ideal elastic collision.

How can two cars have equal and opposite momentum if travelling at differen speeds?
Different weights and traveling in opposite directions.
What the momentum between two identical balls traveling toward each other at thae same speed from opposites direction?
The momentum of one ball will be exactly the opposite of the momentum of the other ball. The total momentum in this case will be zero.
Can momentum have a negative velocity?
No, momentum can not have a negative velocity. Velocity is the rate of motion of a body from one position to another position in a particular direction. Bodies traveling in opposite directions may appear to have a negative velocity in relationship to each other but any amount of velocity is positive.
When an object with a momentum of 80 kg x ms collides with an object with a momentum of -100 kg x ms what is the total momentum?
If the forces are in the same direction, add them and if they're in opposite directions, subtract them. I'm not sure what to do if they're in directions other than that.
Why if total momentum is zero but kinetic energy is not equal to zero?
This sounds like a trick question. Momentum has a sign (positive or negative), and if you have two masses that are going in opposite directions their total momentum is zero. But the sum of their kinetic energies is positive.

Why do electron n positron move in opposite directions in pair production and how does momentum is conserved when they move in opposite directions?
They move in opposite directions when in a magnetic field because they have opposite charges. The force on a particle depends on its charge -- make the charge completely opposite, and the force on it will be completely opposite. Momentum is conserved when they move in opposite direction (that is, in their center of mass frame) because their respective masses are identical. One electron mass moving in one direction plus one electron mass moving in the opposite direction means a total momentum of zero. The system begins with zero momentum and ends that way.
White lines separate traffic traveling in opposite directions?
yes

Two cars leave the gas station in opposite directions one is traveling 50miles per hour and the other is traveling 45miles per hour how many hours will they be 380 miles apart?
If they are traveling in opposite directions, then they are traveling away from each other at a speed of 95 miles per hour. 380/95=4 They have been traveling for four hours.
Damage is more when two bodies collide from opposite directions than when they collide at any other angle.Is it due to the momentum of the objects or their relative velocities?
It is due to the momentum of the two bodies.
How is momentum conserved in pair production?
Basically, the two particles fly off in opposite directions.Basically, the two particles fly off in opposite directions.Basically, the two particles fly off in opposite directions.Basically, the two particles fly off in opposite directions.
When a cannon is fired the cannon and cannon ball will have the same amount of kinetic energy?
No they won't. But they'll have the same momentum, in opposite directions.
