An apple falls from an apple tree growing on a 20° slope. the apple hits the ground with an impact velocity of 16.5 m/s straight downward. what is the component of the apple's impact velocity parallel to the surface of the slope?

There are two components we are looking for and these are:
1. The velocity component down the slope and

2. The velocity component straight into the ground
So the formula for the first one is:

V*sin(angle); plugging in the information given, we have: = 16.5 m/s * sin (20°) = 5.6 m/s
So for the second one is:

V*cos(angle) = 16.5 m/s * cos(20°) = 15.5 m/s
