A toboggan approaches a snowy hill moving at 15.0 m/s. The coefficients of static and kinetic friction between the snow and the toboggan are 0.460 and 0.350, respectively, and the hill slopes upward at 41.0 above the horizontal. Find the acceleration of the toboggan as it is going up hill, and find the acceleration after it has reached the highest point and is sliding down hill.
