A skier is accelerating down a 30.0° hill at a = 3.70 m/s2 (
(a) What is the vertical component of her acceleration?
(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?
vertical component? 3.70*sinTheta
b) distance= 310/sinTheta
distance= 1/2 a t^2 solve for t.
