A 1.0 g particle has momentum 400,000 kgm/s. What is the particle’s speed in m/s?

The speed of particle is .

See the step by step solution

Given information

We have given that, a 1.0 g particle has momentum 400,000 kgm/s.

Step 1.

We will use relativistic momentum formula to get the value of photon's velocity.

Formula of relativistic momentum is :

Here, m = mass of photon

v = velocity of photon

c = speed of light

= relativistic density

Step 2.

Substituting the values in the formula :
