When carts unequal masses push away from each other which cart has more momentum?

In elastic collisions, momentum is a completely conserved quantity, meaning that the total momentum of the system before the collision should equal to the total momentum of the system after the collision. In this case, the p initial was equal to 0, that means p final should have also been 0, the only way that could be achieved is if the momentum of both carts had the same magnitude but in the opposite direction. p = m*v so if p is the same, the cart with the heavier mass would necessarily have a slower speed than the light cart.

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 objects with different masses have the same momentum?
Yes. Momentum is rigidly defined as the product of mass and velocity. Velocity describes both a speed and a direction. So let's take two metal balls. One weighs 10 kilograms (kg) and the other weighs 20kg. We roll the 10kg ball along a flat and level floor at 2 meters per second (m/s) and the 20 kg ball at 1 m/s. 10*2 = 20*1 so they have the same momentum. If you have a friend roll the balls for you to catch some distance away, making sure after a few tests to roll the lighter ball at twice the speed of the heavier ball, you will find that it "feels" as if both balls hit your hand with about the same force. Your hand is stopping each ball. That is a force which is defined as the rate of change in momentum. Stopping each ball will cause your muscles to exert about the same strength to stop each ball, even though one is moving at double the speed of the other. You will then feel that two objects can indeed travel at different speeds and yet have the same momentum. JGS
Why is the third law called the law of conservation of momentum?
Since the force is the same in both directions, whatever momentum one object gains, the other loses.Since the force is the same in both directions, whatever momentum one object gains, the other loses.Since the force is the same in both directions, whatever momentum one object gains, the other loses.Since the force is the same in both directions, whatever momentum one object gains, the other loses.
What is the total momentum of the system before collision If two 0.5 kg balls approach each other with the same speed of 1.0 ms?
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.
Which can be described as in an isolated system momentum is always conserved?
Briefly, the only way for an object to change its momentum is by transferring momentum to another object - in other words, the other object will receive a change in momentum in the opposite direction.
What keeps asteroids moving through space?
the gravity of large masses. the large masses could be other planets or stars or our sun Their own momentum. other masses only deflect them by changing their momentum.
Momentum of a system is conserved only when?
When no momentum is exchanged with other objects/systems.When no momentum is exchanged with other objects/systems.When no momentum is exchanged with other objects/systems.When no momentum is exchanged with other objects/systems.
In two boys of unequal weights running towards each other with the same speed meet lead-on what is the result of the collision?
The lighter boy will be moved backwards by a force equal to the difference in their masses.
Can gold be found in shopping carts?
No, gold cannot be found in shopping carts. Gold can be in other places, but it cannot be found in shopping carts.
Why does earth rotate constantly?
Actually it doesn't - but the changes are quite small. There is a physical law called Conservation of Angular Momentum - the total angular momentum (informally, we might say the "amount of rotation") can't increase or decrease in a closed system. If the distribution of masses on Earth changes, Earth's angular velocity can change - but any redistribution of masses is rather small-scale, compared to the size of the Earth. On the other hand, Earth rotates slower and slower over time - angular momentum is transferred to the Moon in this case.
What is quadrilateral whose diagonals are perpendicular to each other but unequal?
It is a kite or a rhombus both of which have unequal diagonals that are perpendicular to each other creating right angles.
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.
What all masses exert on other masses?
