A toboggan approaches a snowy hill moving at 14.8 . The coefficients of static and kinetic friction between the snow and the toboggan are 0.390 and 0.250, respectively, and the hill slopes upward at 43.0 above the horizontal.
Part A Find the acceleration of the toboggan as it is going up the hill. Assume axis directed up the hill.
Part B Find the acceleration of the toboggan after it has reached its highest point and is sliding down the hill. Assume axis directed up the hill.
