Problem

A uniform meter stick is pivoted at its center. A

4\,\text{N}

force is applied upward at the

25\,\text{cm}

mark, and a

4\,\text{N}

force is applied downward at the

75\,\text{cm}

mark. Neglect all other forces. Which of the following best describes the stick’s immediate motion? (a) Translational acceleration is zero; angular acceleration is nonzero and counterclockwise. (b) Translational acceleration is nonzero upward; angular acceleration is zero. (c) Translational acceleration is zero; angular acceleration is nonzero and clockwise. (d) Translational acceleration is zero; angular acceleration is zero.
