Solve the all parts of given question:

Question: A toboggan approaches a snowy hill moving at 14.7m/s. The coefficients of static and kinetic friction between the snow and the toboggan are 0.450 and 0.350, respectively, and the hill slopes upward at 42.0 degrees above the horizontal.

Part I: Find the acceleration of the toboggan as it is going up the hill. Assume +x axis directed up the hill.

Part II: Find the acceleration of the toboggan after it has reached its highest point and is sliding down the hill. Assume +x axis directed up the hill.

Please give a full detailed explanation of solution.
