Speed of particle is 0.707c.

See the step by step solution

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 :
