I'de love to know what happens to a vehicle in a collision and the principles that apply here
[ if a car collides into a stationary vehicle: before the collision, [ the momentum is equal to only the momentum of the moving car, because the stationary car has no velocity, and therefore no momentum after the collision, [ the two objects "stick" together and move with one total velocity. because the mass of the two cars together is greater than the mass of the moving car by itself, it must be true that the velocity is now less than the car was moving before. (of course the car that was stationary has a greater velocity than it had before because it wasn't even moving) the formula for
this situation, if you had numbers, would be: m1v1 + m2v2 = (m1 + m2)v3 the left side is before, the right side is after rememer that v2 = 0 if a car collides into a car moving in the same direction: before the collision the car that is behind is traveling at a faster velocity than the car in front, because thats the only way that it can even catch up with the other car. what happens after the collision is that the cars will stick together and move at one velocity. this velocity will be somewhere in between the initial velocities of the two cars (for example, if one of them had v = 1 and the other had v = 2, then the velocity of them after the collision would be between 1 and 2) if you had numbers you would use the same formula as the first example if a car collides into a car moving in the opposite direction (towards it): this would depend on the velocity of each car in comparison to the other. if the cars were traveling at the same exact speed, then they would both stop after the collision. if they were traveling at different speeds, then the cars would move in the direction of the car that was moving faster, but at a slower speed than before. again, with numbers you would have the same formula however, you have to remember that you have to choose a positive and negative direction. this is vital because the cars are moving in different directions hope this helps! ] ] ]
