Askier is accelerating down a 30.0 degree hill at 3.80 m/s2. how long (in seconds) will it take her to reach the bottom of the hill, assuming she starts from rest and accelerates uniformly, if the elevation change is 130 m?

t = 11.69s

Explanation:

The distance traveled by the skier is given by:

  where H=130m

D = 260m

Now, the movement down the hill is described by:

 Solving for t:

explanation:

a fuel engine ( known as a gasoline engine in american english )is an internal combustion engine with spark ignition, designed to run on petrol (gasoline) and similar volatile fuels.

wavelength divides in half and speed stays the same.
