# Elastic Collision Relative Velocity

### Relative velocity part 5 high school help.

**Elastic collision relative velocity**.
The collision could also be elastic or inelastic or anywhere in between momentum is always conserved without an outside force but in some collisions perfectly elastic.
Find the final velocity of each particle in the laboratory frame this is where im getting confused.
The angle between the force and the relative velocity is obtuse then this potential energy is converted back to kinetic energy when the particles move with this force ie.
Also for the kinetic energy how long it remains for the objects to bounce from each other.

The one thing we do know is that if the collision is elastic the speed of the ping pong ball relative to the bowling ball must be the same after the collision as it was before the collision. After the elastic collision the particles separate so that particle 1 as viewed from particle 2 moves away along the positive x axis ie. Collisions of atoms are elastic for example rutherford. Ke 12 mv 2 so heres your equation for the two cars final and initial kinetic energies.

A 700 kg ice hockey goalie originally at rest catches a 0150 kg hockey puck slapped at him at a velocity of 350 ms. In a 1d elastic collision it is well known that the relative velocities of the two objects before and after the collision are reversed. The angle between the force and the relative velocity is acute. Before the collision the speed of the ping pong ball relative to the bowling ball was just equal to v.

In the direction of the unit vector i. When you say reversed do you mean that each object keeps their own velocity just with a change of sign. Now you have two equations and two unknowns v f 1 and v f 2 which means you can solve for the unknowns in terms of the masses and v i 1. Cor e relative velocity after collisionrelative velocity before collision range of coefficient of restitution.

That would not always be the case for a 1d situation. The elastic collision formula of kinetic energy is given by elastic collision formula is applied to calculate the mass or velocity of the elastic bodies. The collision was elastic so kinetic energy was conserved. For cor range its between 0 and 10.

If the two satellites collide elastically rather than dock what is their final relative velocity.

Do you need anything, like a medicine maybe?
