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
