The initial momentum is M1U1 + M2U2 where M1 and M2 are the masses of the two cars (in kilograms), and U1 and U2 are their velocities (in metres per second).
After a collision,The initial momentum of a system is equal to final momentum. m1V1=m2V2
momentum
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
how an information system can reduce uncertainty
There are two possible results. However, they cannot move in the same direction after the collision.Total initial momentum = p - p = 0where p represent the momentum of each object.From the principle of conservation of momentum;Total initial momentum = Total final momentumThus, Total final momentum = 0There are only two possibilities for this:1. Kinetic energy is conserved. (the collision is perfectly elastic)In this case, they would move away from each other with the same magnitude of initial momentum.2. Kinetic energy is not conserved. (the collision is inelastic)In this case, they would either remain at rest or they will move away from each other with a smaller magnitude of initial momentum each had.Note that if both bodies had moved in the same direction, there would be a net momentum in this direction and momentum would not have been conserved. (Momentum is ALWAYS conserved provided there is no external force acting on the system)

To calculate the velocity after a perfectly elastic collision, you need to apply the principle of conservation of momentum and kinetic energy. First, find the initial momentum of the system before the collision by adding the momenta of the objects involved. Then, find the final momentum after the collision by equating it to the initial momentum. Next, solve for the final velocities of the objects by dividing the final momentum by their respective masses. Finally, make sure to check if the kinetic energy is conserved by comparing the initial and final kinetic energy values.

In symbols, linear momentum p is defined to be p = mv, where m is the mass of the system and v is its velocity. The SI unit for momentum is kg ยท m/s. Newton's second law of motion in terms of momentum states that the net external force equals the change in momentum of a system divided by the time over which it changes.

The law of conservation of momentum states that the energy lost initially by the first object is equal to that gained by the last object in an isolated system. This is the principle behind perpetual motion. The only difficulty is that it is difficult to find a truly isolated system.Ê
The idea is to use conservation of momentum. Calculate the total momentum before the collission, add it up, then calculate the combined velocity after the collision, based on the momentum.
the Law Of Conservation Of Momentum or 'LOCOM' states that total momentum is constant. in other words initial momentum= final momentum...if you don't understand that, then............ LOCOM states that... PROVIDED THAT THERE ARE NO EXTERNAL FORCES ACTING ON A SYSTEM OF COLLIDING BODIES,THE VECTOR SUM OF THE MOMENTA BEFORE COLLISION IS EQUAL TO THE VECTOR SUM AFTER THE COLLISION.----------------> =
For momentum to be conserved in a system it must
The linear momentum of a system of particles is simply the vector sum of the linear momentum of each of the particles.
