How does the speed of the combined cars compare to the speed of the car before the collision when a parked car is hit by a moving car and the two cars stick together?

The combined VELOCITY of two cars that crash will be somewhere between that of the individual cars. In this case, the combined speed will be less than the speed of the car that was moving before the crash.If you know the velocities and the masses, the exact speeds can be calculated using conservation of momentum.

How does the momentum of two objects before a collision compare with the momentum after the collision?
conservation of momentum
Two balls of masses 500gram and 200 gram are moving at valocities 4m s and 8m s respectively on collision they stick together find the velocity af the system after collision?
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.
In an isolated system two cars each with a mass of 1000 kg collide Car 1 is initially at rest while Car 2 was moving at 10-ms They move off together What is their speed?
Since momentum must be conserved, they move off at a combined speed of 5 m/s. (If the masses are different, write an equation that states that momentum is conserved: momentum before the collision equal momentum after the collision).
What is the total momentum of marbles after the collision?
The same as the total momentum before the collision.
How momentum is conserved in pair production before and after collision?
That means that total momentum doesn't change. It is the same before and after the collision.

If a moving boxcar gently collides with a boxcar at rest and the two boxcars move together what will their combined momentum be?
Their combined momentum will be equal to the first boxcar's original momentum before the collision.
What happens to the total momentum of two objects in a system before and after interactions?
The total momentum before the collision is the same as the total momentum after the collision. This is known as "conservation of momentum".
Two balls of masses 500gram and 200 gram are moving at valocities 4m s and 8m s respectively on collision they stick together find the velocity af the system after collision?
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.
How is momentum conserved after a collision?
Completely If you add all the energy of all the resultants of the collision together, you will arrive at the same value as the sum of the energies of all the components before the collision.
If m1 is 2kg and sticks to m2 which is 1kg after the collision what is the velocity of the combined mass immediately after impact?
We know that momentum is conserved, so we'd have no trouble answering that question if you had just told us what their velocities were before the collision.
Did the catcher and ball together have the same speed as the ball alone after colliding?
No. The thing that is the same before and after the collision is the total momentum.
In an isolated system two cars each with a mass of 1000 kg collide Car 1 is initially at rest while Car 2 was moving at 10-ms They move off together What is their speed?
Since momentum must be conserved, they move off at a combined speed of 5 m/s. (If the masses are different, write an equation that states that momentum is conserved: momentum before the collision equal momentum after the collision).
What is the total momentum of marbles after the collision?
The same as the total momentum before the collision.
How momentum is conserved in pair production before and after collision?
That means that total momentum doesn't change. It is the same before and after the collision.
In an isolated system two cars each with a mass of 1500 kg collide. Car 1 is initially at rest while Car 2 was moving at 5 ms. What is their combined momentum after the collision?
Law of Conservation of Momentum: The total momentum after the collision is equal to the total momentum before the collission.
Is it possible for you to get travel insurance policy and discount tour while abroad?
The cheaper and wiser option here would be to get an annual plan that provides you with worldwide coverage and discount trip option. This is a dual insurance plan combined together. Compare well before choosing a plan.
