Suppose that 1st car is X-car and the 2nd car is Y-car.
Answer: After the collision, car X is no linger moving, but car Y is moving.

Suppose a train car in moving down the track at 10ms hits another train car that is not moving explain how momentum is conserved after the collision?
Conservation of Momentum:The total momentum in a closed or isolated system remains constant. If the two trains are moving as one after the collision, and were the same mass M each, the total momentum before and after the collision would be the same, ccording to the law. Before the collision, the momentum (velocity times mass) was 10 x M units (one train) which must now be the same but applied to two trains (2M) moving as one body. The Conservation of Momentum rule, will tell you that the new moving body, being twice the mass, would be moving half the velocity to conserve the momentum from before the collision.
How many times greater is the force of collision if the driving speed is doubled?
Answer: It depends. The "force" of the impact depends on the momentum of the object. Momentum depends on mass and velocity. If the mass and velocity are constant, then extending the time of impact will not change the momentum. Suppose you stand 10 feet away from me and I throw a brick at your face. Then suppose you stand 40 feet away and I throw the same brick at your face. It's going to hurt you about the same amount (ignoring gravity and air resistance). Suppose you are 40 feet above me and I throw a brick at your face. It will hurt less, because gravity will be slowing down the brick. Suppose I am 40 feet above you and I throw a brick at your face. It will hurt more, because gravity will be speeding up the brick. john
Suppose two identical spheres are given charges of 4g and -g respectively if they are brought into electrical contact and then separated what charge is retained by each sphere?
Charge is conserved. Apply symmetry.
How does increase in mass affect the time taken?
Oh, it's tricky. But if you are in Physics 30 + it should be easy. First, the concept of Momentum and impulse is in here. So, first conservation of momentum law guarantees that the momentum before Math added is equal to the momentum after the mass added. Suppose the momentum is A. M : = Momentum = mv. v = M/m so velocity changes. So, if it's slower, does it takes longer or shorter time to travel the same distance? What about when velocity is faster. Remark: as m, mass, increases, the velocity decreases.

Is the direction of angular velocity same as that of angular momentum when agular velocity is decreasing?
Yes, suppose a body is rotating anti-clockwise, then its angular velocity and angular momentum, at any moment are along axis of rotation in upward direction. And when body is rotating clockwise, its angular velocity and angular momentum are along axis of rotation in downward direction. This is regardless of the fact whether angular velocity of the body is increasing or decreasing.
Suppose you have two toy cars each has a mass of 0.04kg the cars have tape on their bumpers that will cause them to couple together one car is stopped on the track the car what is the momentum of cars?
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)
