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

vertical component? 3.70*sinTheta

b) distance= 310/sinTheta
distance= 1/2 a t^2 solve for t.
