Finding momentum components from Fermi Lab particle physics data

[imda8o8bomb]

Help me if you can! Particle physics! Give it a shot! Pleaseee

in particle physics data from fermi lab I have to find out the momentum (p) of x, y, and z. The equation is p=qBx and i have q(coulombs) and B (tesla). The data I'm looking at says

cos theta x=0.47

cos theta y=-.10

cos theta z=-.88

using q=1.609E-19 and B=4
how can I find p x, p y, p z?

I'm not sure I understand what you've written out there correctly.

cos theta x = 0.47?

Do you mean x(cos (θ)) = 0.47 ?

Also, for p = qBx, is that x a subscript or a variable?
