2) The rod AB rotates about point A with an angular displacement of $\theta = 3t^2 - 2t$, where $\theta$ and $t$ are expressed in radians and seconds, respectively. The collar C slides along the rod so that its distance from point A is $r = 4t^2 - 3t^2$, where $r$ and $t$ are expressed in meters and seconds, respectively. Determine the velocity and acceleration of the collar when $t = 2$ s. Hint: $v = \dot{r} + r\dot{\theta}$ $a = (\ddot{r} - r\dot{\theta}^2)\hat{e}_r + (r\ddot{\theta} + 2\dot{r}\dot{\theta})\hat{e}_\theta$

6) Let $F(x, y) = \begin{bmatrix} \sin(y) - y^2 + 1 \\ x \cos(y) - 2xy \end{bmatrix}$. Is $F$ conservative? If so, give a potential function for $F$. 7) Let $F(x,y) = \begin{bmatrix} \sin(y) - y^2 + 1 \\ x \cos(y) - 2xy \end{bmatrix}$ and let $C$ be the curve $(t^2, 2(\pi - t))$, where $1 \le t \le 2$. Use your work from question 6 to evaluate: $\int_C F \cdot dr$
