Answer to Question #185467 in Physics for Chene

Question

An apple falls from an apple tree growing on a 20° slope. The apple hits the ground with an impact velocity of 16.2 m/s straight downward. What is the component of the apple's impact velocity parallel to the surface of the slope?

Answer 1

$$v_x=v\sin{20}\\v_x=16.2\sin{20}=5.54\frac{m}{s}$$
