oh i totally forgot about gamma portion of the equation! Thanks for the help!

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 Impulse = mV_f{}-mV_i{} The Attempt at a Solution Impulse = mV_f{}-mV_i{} = 1.7e-27*(.994*3e8)-(1.7e-27*(.991*3e8)) =...

oh ok i got it. you can't add those two together because one is a momentum vector and the other is a net force. so the change of direction would be just in the direction that the force was applied

I thought this question was fairly simple but apparently I'm getting the wrong answer 1.A ball moves in the direction of the arrow labeled g in the figure (which points left or west direction). The ball is struck by a stick which briefly exerts a force on the ball in the direction of the arrow...
