What is the magnitude of the impulse required in the direction of motion to increase its speed?

A proton has mass 1.7 *10-27 kg. What is the magnitude of the impulse required in the direction of motion to increase its speed from 0.994c to 0.997c?What is the magnitude of the impulse required in the direction of motion to increase its speed?the magnitude of the impulse is equal the change in momentum, or mass times change in velocity. Since the velocity is so high in this case however, you must use the formula for momentum = mass * volume * (1/sqrt(1-(v/c)^2)). Use this formula to calculate initial and final momentum and then find the difference and that will be your answer.
