7. 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,
A. v1 = 5.66 m/s, v2 = 11.3 m/s.
B. v1 = 14.1 m/s, v2 = 7.07 m/s.
C. v1 = 11.3 m/s, v2 = 5.66 m/s.
D. v1 = 22.6 m/s, v2 = 11.3 m/s.
E. v1 = 14.1 m/s, v2 = 22.6 m/s.
