A proton with initial speed 158,008 m/s is accelerated through a certain potential difference V and as a result, the proton's speed increases to 331,229 m/s. What was the magnitude of the potential difference through which the proton was accelerated? ($e = 1.602 \times 10^{-19}$ C and $m_p = 1.67 \times 10^{-27}$ kg, and report your answer in volts with three significant digits.)
