An apple falls from an apple tree growing on a 20° slope. The apple hits the ground with an impact velocity of 2.6 m/s straight downward. What is the component of the apple's impact velocity parallel to the surface of the slope.
I don't really understand what they mean by 20 degrees slope, what formula do I use?
