A 75-kg snowboarder has an initial velocity of 5.0 m/s at the top of a 28 degree incline. After sliding down the 110-m-long incline (on which the coefficient of kinetic friction is μk= 0.17), the snowboarder has attained a velocity v. The snowboarder then slides along a flat surface (on which μk= 0.14) and comes to rest after a distance x. Determine BOTH the snowboarder's acceleration on the incline AND his acceleration on the flat surface. Then, determine x.
