Homework Statement
A proton has mass 1.7×10−27 kg. What is the magnitude of the impulse required to increase its speed from 0.991c to 0.994c?
Homework Equations
[tex]Impulse = mV_f{}-mV_i{}[/tex]
The Attempt at a Solution
[tex]Impulse = mV_f{}-mV_i{}[/tex]
[tex]= 1.7e-27*(.994*3e8)-(1.7e-27*(.991*3e8))[/tex]
[tex]= 5.0694e-19 -5.0541e-19[/tex]
[tex]Impulse = 1.53e-21[/tex]
I've triple checked my work and I still come up with the same wrong answer. Am I missing something here??
