(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

One car has one and a half times the mass of a second car, but only half as much kinetic energy. When both cars increase their speed by 8.0 m/s, they then have the same kinetic energy. What were the original speeds of the two cars?

2. Relevant equations

ke = (1/2)mv^2

3. The attempt at a solution

m1 = 1.5m2

k1 = k2/2

(1/2)(1.5m)(v1+8)^2 = (1/2)(m)(v2+9)^2
