J
Integration question, u substitution
The problem statement Evaluate the indefinite integral ∫\frac{\sqrt{x}}{\sqrt{x}-3}dx The attempt at a solution My first thought was to substitute u for √(x)-3, but then du would equal \frac{1}{2\sqrt{x}}dx, and there's no multiple of du in the integrand. Next, I tried splitting up...- jonc1258

Velocity of a steel ball bearing due to magnetic force
27.1 = .005a a = 5420m/s^2 v^{2}_{f} = v^{2}_{i} + 2ad v^{2}_{f} = (0) + 2(5420)(.1) vf^2 = \sqrt{1084} v=32.9m/s Yes?- jonc1258
