Velocities Corresponding to Sample Position Functions Since we know that v(t) = x'(t) , we can now use our new knowledge of derivatives to compute the velocities for some basic position functions: for x(t) = c , c a constant, v(t) = 0 (using (F2)) for x(t) = at 2 + vt + c , v(t) = at + v (using (F1),(F2),(P1), and (P2))

(4) is popularly known as "distance equals rate × time."...
