# Relativistic Momentum Problem

## Homework Statement

At what speed is the magnitude of the relativistic momentum of a particle 11 times the magnitude of the nonrelativistic momentum?

## Homework Equations

P=mv/(1-v^2/c^2)^1/2

## The Attempt at a Solution

11=v/(1-v^2/c^2)^1/2?

Essentially, the question asks you to solve for v, when $$\gamma = 11$$.
