What were the original speeds of the two cars

Reference no: EM13711797

Problem: The first car has twice the mass of a second car, but only half as much kinetic energy. When both cars increase their speed by 9.0m/s , they then have the same kinetic energy.

Part A: What were the original speeds of the two cars?

I need help to find what the original speeds of the two cars.
