I didn't think there was anything missing, this is just me being paranoid I guess. Thank you

A person drives a car over the top of a hill, the cross section of which can be approximated by a circle of radius r=250m. What is the greatest speed at which he can drive without the car leaving the road at the top of the hill? I know that the maximum speed occurs when the normal force=...

So, just to be clear, if acceleration is (2.5-x^2)/m. I can write velocity as v= -1/3x^3+2.5x/mass?

how can i find velocity if force is not constant, but a function of distance. I tried integrating the equation for the force, but that doesn't account for the mass of the object. the given equation for the force is F(x)=2.5-x^2, where x is distance and since F=ma I have a=(2.5-x^2)/m...
