Relativistic momentum in terms of another relativisic momentum

[QUOTE="Sconlan, post: 6849286, member: 732998"] [B]Homework Statement:[/B] When the ship passes at velocity V1, the shuttle pilot measures the magnitude of the momentum of the spaceship to be p1. On a subsequent mission, the spaceship again passes the shuttle, this time at twice the previous velocity, V2 = 2V1 = 0.840c. The shuttle pilot again measures the momentum of the spaceship. In terms of p1, what is the magnitude of the measured momentum of the spaceship this time? [B]Relevant Equations:[/B] The relativistic momentum p of a material particle of mass m and velocity v is defined by the following vector equation: p=mv/√(1-v^2/c^2 ) The total relativistic energy of a particle m travelling at speed v is given by: E_tot=(mc^2)/√(1-v^2/c^2) = E_trans+E_mass. Where: E_trans = ((mc^2)/(1-v^2/c^2))-mc^2 And E_mass = mc^2 The relationship between the total relativistic energy and the magnitude of the relativistic momentum can be expressed as: (E_tot)^2 = p^2c^2+m^2c^4 I feel like this should be pretty straightforward knowing all the equations involved but my brain seems be stalling for some reason.
