Two cars are moving. The first car has twice the mass of the second car, but only half as much kinetic energy. Then, both cars increase their speed by 8.00 m/s. They then have the same kinetic energy. The original speeds of the two cars are, respectively, 22.6 m/s, V2 = 11.3 m/s. A V; = 5.66 m/s, V2 = 11.3 m/s. B V1 = 14.1 m/s, vz = 7.07 m/s. V1 = 11.3 m/s, v2 = 5.66 m/s. D
