Question

A particle is moving with 90% of the velocity of light compare its relativistic mass with its rest mass​

Answer 1

When the particle is moving with 90% of the velocity of light compare its relativistic mass with its rest mass​ and 90) p0 = p0 cosh u + px sinh u. Here v is the velocity of the object.

The inertial frame we’re observing it through, and c is the velocity of light.

Now the relation between the two masses is: Relativistic mass = γ * Rest Mass.
