Find the tangential and normal components of acceleration of an object that moves along the parabolic path y=4x^2 at the instant the speed ds/dt=5.

I know how to find the both these given a vector but no idea when given just a path and speed. i figured i had to solve for the curve but the problem doesn't even give me a point so im lost.
