![**Problem 4: Work Done by a Force Field along a Parabolic Path**
Find the work done by the force field \(\vec{F}(x, y) = \langle 2y, x \rangle\) acting on an object as it moves along the parabola \(y = 2x^2\) from the point \((3, 18)\) to \((0, 0)\). The expression for the work done is given by the line integral:
\[
\int_C 2y \, dx + x \, dy
\]
**Problem 5: Work Done by a Force Field along a Vector-Valued Path**
Find the work done by the force field \(\vec{F}(x, y) = \langle x^2, xy \rangle\) acting on an object that is moving along the direction of the vector-valued function:
\[
\vec{r}(t) = \langle 3t, 2t \rangle, \quad 0 \leq t \leq 1
