At What Velocity Would a Proton Be Traveling If It

At what velocity would a proton be traveling if it had the same kinetic energy as an electron traveling at 10.0% of the speed of light? KE = ½ mu², where m is the mass and u is the velocity; proton mass = 1.673 *10^-27 kg; electron mass = 9.109 * 10^-31 kg; speed of light = 2.998 -10⁸ m/s.

A) 4.89 *10¹¹ m/s
B) 2.45 * 10¹¹ m/s
C) 4.95 * 10⁵ m/s
D) 7.00 * 10⁵ m/s
E) 3.50 *10⁵ m/s
