get a speedometer
There are not any answers to the velocity test online. People looking for the answers will need to review the course textbooks.
Velocity of the x axis (how fast it's moving to the side) remains constant, so it equals whatever the x axis velocity is.
Since the mass of both cars is .04 kg and the one car is hitting the first car at a velocity of 4 m/s, you would calculate the momentum of the cars by using the Law of Conservation of Momentum (Which states that the total momentum of a moving object remains constant when interacting with another object). To calculate momentum you would find the product of mass and velocity, which the problem states.Equation:The mass x The velocity = The Momentum.04 kg x 4m/s = .16 (kg m/s)Answer: .16 (kg m/s)

You can't, because you don't have enough information. In order to find velocity, you need to be able to find the speed and the direction of motion. You have the speed, but you have no information that you can use to determine the direction in which the object is moving. Mass doesn't help.
Momentum of a moving body is got by the product of the mass and velocity. Hence P = m v Momentum is a vector quantity Its unit in SI system is kg m s-1
You calculate the charge in velocity, not in distance.
When you combine 2 velocities that are in the same directions, add them together to find the resultant velocity. When you combine 2 velocities that are in opposite directions, subtract the smaller velocity from the larger velocity to find the resultant velocity.

To find the magnitude of momentum you use the formula: p=mv So, if an object has a mass (and if it exists then it would), and if it is moving (has a velocity), then yes, it has momentum.
you would dived the distance by the time it takes to find the velocity.
