A 0.20-kilogram solid rubber ball is attached to the end of an 0.60-meter length of light thread. The ball is swung in a horizontal circle. At one point along the circular path, the speed of the ball is 5.0 meters per second. The following diagram shows a downward view of the horizontal path. 5.0 m/s 0.60 m a b a. Using a dot model, draw and label all the forces exerted on the ball when it is at point b. (3 points) b. Determine the speed of the ball at point a. Show your work. (4 points) c.

9. Let \begin{pmatrix} 1 & -3 & -3 \\ 3 & -5 & 3 \\ 6 & -6 & 4 \end{pmatrix} Eigenvalues $\lambda = 4, -2$ (repeated) $\vec{v}_1 = \begin{pmatrix} 1 \\ 1 \\ 2 \end{pmatrix}, \vec{v}_2 = \begin{pmatrix} 1 \\ 0 \\ 1 \end{pmatrix}, \vec{v}_3 = \begin{pmatrix} -1 \\ 1 \\ 0 \end{pmatrix}$ $\vec{v}_1, \vec{v}_2, \vec{v}_3$ are the eigenvectors corresponding to the eigenvalues 4, -2, -2 respectively Use this information to diagonalize A. 10. Diagonalize the following matrices, if possible. (a) $A = \begin{bmatrix} 3 & 1 & 1 \\ 1 & 3 & 1 \\ 1 & 1 & 3 \end{bmatrix}$ (b) $B = \begin{bmatrix} 1 & 2 & -3 \\ 2 & 5 & -2 \\ 1 & 3 & 1 \end{bmatrix}$
