a golf ball is launched at a 37 degree angle from the horizontal at an initial velocity of 48.6 m/s. state the initial velocity in rectangular coordinates.

please show me how to figure this out

1 answer

Vo = 48.6m/s @ 37deg.

Vo(h)=48.6cos37 = 38.8m/s = hor. comp.
Vo(v)=48.6sin37 = 29.2m/s = ver comp.

Rectangular Form:
Vo = 38.8 + j29.2 m/s.

The "j" means there is a 90 degree
phase difference between the 2 vectors.
