Is momentum conserved during an instantaneous stop of two carts colliding?

Question

The exact questions is: At the moment that two carts collide, they both experience an instantaneous stop. Is momentum conserved during the stop? Give reasons for your answer.

Answer 1

Well momentum is not conserved during a stop because it will have no momentum because it has no motion. I just learned this recently in my science class.

Answer 2

Momentum is CONSERVED this is because momentum is a vector quantity which means it has direction associated with it. Since the carts were moving in opposite directions when they collided then they stopped so you also know that they had the same momentum when they collided.

Answer 3

Yes, if any two things collide, they will have different momentum,i.e, how small or how slow, it is, or how fast and big it is. This is that the center of mass of any system of objects will always continue with the same velocity unless acted on by a force outside the system. So it is conserving it?

Answer 4

p =mv momentum = mass* velocity initially the two carts had some form of momentum, because of the fact the two have mass and the two had some form of velocity. on condition that they the two got here to an entire provide up, the preliminary velocity became into lost. because of the fact the preliminary velocity became into lost, then in accordance to the formulation, preliminary momentum is likewise lost meaning...No, momentum isn't conserved.

Answer 5

Both cannot experience an instantaneous stop unless if they have equal and opposite momentum before impact.

Answer 6

I think i know this, momentum is always conserved in collisions, i think the equation is:
m1v1+m2v2=m1u1+m2u2
v is the velocity before collision
u is the velocity after collision
but the kinetic energy is not conserved if the collision was inelastic such as this one..
