A toboggan approaches a snowy hill moving at 12.1 m/s. The coefficients of static and kinetic friction between the snow and the toboggan are 0.47 and 0.35, respectively, and the hill slopes upward at 40.0 degrees above the horizontal. 1) Find the magnitude of the acceleration of the toboggan after it has reached its highest point and is sliding down the hill. Express your answer in meters per second squared. 2) What is the direction of the acceleration as the toboggan is sliding down the hill?
