Question: A skier is accelerating down a 30.0 degree hill at 1.80 m/s2. What is the vertical component of her acceleration? How long will it take her to reach the bottom of the hill, assuming she starts from rest and accelerates uniformly, if the elevation change is 325 m? The response must be typed, single spaced, must be in times new roman font (size 12) and must follow the APA format.
