Is velocity conserved in elastic conditions?
Nah, brah. Momentum and kinetic energy are conserved, but velocity is not. Correct me if I am wrong but from how I interpret this, any collision cause the colliding bodies to change their direction. Thus velocity, which is a vector quantitiy containing direction, is by definition changed in an elastic collision. I guess speed, which is the magnitude of the velocity, can be considered as being conserved?
There are three collision that make up every collision what happens during the third collision?
The soft tissues of the passengers' bodies collide with the more solid parts of the body, such as the skull, ribs, or pelvis.
How do you find the final velocity of two objects coupled?
The case you're describing is called an inelastic collision. Two objects collide, stick to each other and continue their motion as one body. Due to momentum conservation principle, sum of two bodies momenta before collision has to be equal to momentum of the one body after collision. pbefore = pfirst + psecond = m1v1 + m2v2 pafter = (m1 + m2)vcommon Since pbefore = pafter, (m1 + m2)vcommon = m1v1 + m2v2 We can get vcommon from that: vcommon = (m1v1 + m2v2) / (m1 + m2) [vi are velocities of bodies before collision and vcommon is a velocity after collision]

Why is the law of conservation of momentum useful in analyzing the collision between two bodies?
The law of conservation of momentum useful in analyzing the collision between two bodies because there is use to be the collision between the two bodies reason for that is law of conservation of momentum is that the total sum of momentum is equal means constant after the total sum of momentum of two bodies. so if you don't be the collision between two bodies you will not aware of the meaning of momentum.
What happens to the vehicles in a collision and the principles of elastic and inelastic collisions?
When the collision is perfectly elastic then energy is not lost but exchanged between the bodies collided. So total KE would remain the same before and after collision. But in case of inelastic collision, there would be loss of energy in the form of heat or sound or vibration etc etc. But whether collision is elastic or inelastic the momentum is conserved. That is, the total momentum in a given direction would be the same before and after collision.
What is Principle of conservation of linear momentum?
That means that there is a quantity, called momentum, that is conserved. Momentum is defined as the product of mass times velocity. If you add (product x velocity) for several items, or particles, before and after a collission for example, the total you get will not change. Note that, since velocity is a vector quantity, so is momentum, so if your items move in more than one dimension, you have to use vector addition.
What is A collision between ideally elastic bodies in which the final and initial kinetic energies are the same?
That's called an "elastic collision".
Two billiard balls of equal mass undergo a perfectly elastic head collision. What will be their speeds after the collision.?
The velocities of the two bodies after the elastic collisions are given by V1=(M1-M2)U1/(M1+M2)+2M2U2/(M1+M2) V2=(M2-M1)U2/(M1+M2)+2U1M1/(M1+M2) Where, V1,V2 are the velocities of the two bodies after collision. U1,U2 are the velocities of the two bodies before colision.(U1>U2) M1,M2 are the masses of the two bodies. when the mass of two bodies are equal that is M1= M2 then V1=0+2MU2/2M=U2 V2=0+2MU1/2M=U1 Thus when two billiard balls of equal masses undergo perfectly elastic collision the velocities the two bodies are interchanged after the collision.
What does cosmic collision mean?
a cosmic colision is when two or more bodies in space colide

Probably alcohol.
What is the second most common drug found in the bodies of collision victims?
Marijuana
