Momentum of two vehicles


So obviously ladies and gentlemen the first thing to do not 6.3 but 4.3 the first thing that we need to do is to write the formula ladies and gentlemen you know the sum of momentum initial it's equals to the sum of momentum final okay. What matters the most ladies and gentlemen is for you to know that momentum is equals to mv. What does it mean by that? It's because you've got two vehicles approaching with each other or you've got two vehicles in motion. 

So that sum it means you then need to add the momentum of these two vehicles that's why ladies and gentlemen you've got the sum of momentum as mv plus mv okay. What's the difference ladies and gentlemen? This is for the mass 1 or mass of the car and this will be mass 2 or mass of the track. This will also refer to the velocity of the car or the velocity of that first object. 

So that will be the velocity 2 which refers to the velocity of the second object okay. So ladies and gentlemen because this is the sum of momentum final then this portion focuses on the final scenario. Then this will focus on the initial scenario okay, what is this in a what is the initial scenario this is before the collision, this is before these two objects touches with each other.
