    First Order Differential Equation

    Thanks for the quick reply, so, \frac{dy}{dx} = x(3y + y2) \frac{1}{3y + y^2}dy = x dx However, integrating the left hand side is beyond the scope of the subject I am taking at the moment. That's why they have asked to solve for x, I think. Is it still possible to solve for x using this...

    What Is the Normal Component of Acceleration for Curvilinear Motion?

    Thanks for the reply. I have found a mistake in my calculation of a, more specifically the second order time derivative of y. I agree, when you start to work with these angles it can get a tad confusing, so I'll try your dot product suggestion. I should be on the right track now, I'll post back...
