# What is the speed, as a fraction of c, of a particle whose momentum is mc?

Speed of particle is 0.707c.

See the step by step solution

## Given information

We have given that, particle has momentum mc.

## Step 1.

The formula of relativistic momentum is :

here, m = mass of particle

v = velocity of particle

c = speed of light

= relativistic momentum

We have given that the relativistic momentum is mc.

## Step 2.

Substituting the values in formula :
