I do not see how to do this problem One car has twice the mass of a second car, but only half a smuch kinetic energy. when both cars increase their speads by 7.0 m/s, they then have the sam kinetic energy. What were the original speeds of the cars?

**Calculus URGENT test tonight**

Integral of: __1__ (sqrt(x)+1)^2 dx The answer is: 2ln abs(1+sqrt(x)) + 2(1+sqrt(X))^-1 +c I have no clue why that is! Please help. I used substitution and made u= sqrt(x)+1 but i don't know what happened along the way! Your first step was a good one. next, let u = sqrt x + 1 ...
