Enter the mass and velocity of two objects before the collision to determine the final velocity after the inelastic collision.

## Inelastic Collision Velocity Formula

The following equation is used to calculate the Inelastic Collision Velocity.

V = (M1*V1 + M2*V2) / (M1+M2)

• Where V is the final velocity of both objects after collision (m/s)
• M1 and M2 are the masses of the each object (kg)
• V1 and V2 are the velocities of the objects before collision (m/s)

## What is a Inelastic Collision Velocity?

Definition:

An inelastic collision velocity describes the total final velocity of two objects after an inelastic collision.

## How to Calculate Inelastic Collision Velocity?

Example Problem:

The following example outlines the steps and information needed to calculate Inelastic Collision Velocity.

First, determine the masses. In this example, the masses are found to be 10 kg and 30 kg respectively.

Next, determine the initial velocities. For this problem, these are 40 m/s and 50 m/s respectively.

Finally, calculate the Inelastic Collision Velocity using the formula above:

V = (M1*V1 + M2*V2) / (M1+M2)

V = (10*40 + 30*50) / (10+30)

V = 47.5 m/s
