(a) A skier is accelerating down a 30.0 degree hill at 4.30 m/s^2. What is the vertical component of her acceleration? (m/s^2 (downward))

(b) 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 330 m? (s)

Solution Summary

This solution is provided in approximately 127 words in an attached .doc and .pdf file. It provides an acceleration vector diagram to enhance learning and uses this diagram to find the vertical component of acceleration. Another diagram is used for creating an equation for the vertical component of any vector.
