A firefighter who weighs \( 689 \mathrm{~N} \) slides down a vertical pole with an acceleration of \( 2.00 \mathrm{~m} / \mathrm{s}^{2} \), directed downward. What are the magnitude and Jirection (up or down) of the vertical force on the firefighter from the pole and the magnitude and direction of the vertical force on the pole from the firefighter?
