A toboggan approaches a snowy hill moving at 10.9 m/s. The coefficients of static and kinetic friction between the snow and the toboggan are 0.470 and 0.320, respectively, and the hill slopes upward at 44.0^\circ above the horizontal
A. Find the acceleration of the toboggan as it is going up the hill.
B. Find the acceleration of the toboggan after it has reached its highest point and is sliding down the hill.
