(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Mass of particle = 5GeV/C^2

Momentum of particle = 5GeV/c

Find total energy of particle and speed of particle.

2. Relevant equations

E=λmc^2

p=λmu

λ=(√(1-(u/c)^2))^-1

3. The attempt at a solution

When I try so solve for speed, I realize λ is a function of u, so get this:

(u*(√(1-(u/c)^2))^-1) = p/m = c, but can't solve for u from that.

How would I go about approaching this problem?
