A skier is accelerating down a 30.0° hill at a = 3.70 m/s2 (
(a) What is the vertical component of her acceleration?
m/s2 (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 310 m?
s

physics 
bobpursley,
vertical component? 3.70*sinTheta
b) distance= 310/sinTheta
distance= 1/2 a t^2 solve for t.
