# Physics

A given force F→ is located in the yz-plane. It has a magnitude of 18N and is directed at a 30.0° angle clockwise from the positive y-axis.
(a) Describe F→ using polar notation.
(b) Describe F→ using its y- and z-components.
(c) Describe F→ using cartesian notation.

I have a hard time figuring out this question
For a) I think it's 18m/s[300degrees]
b) Fy= 15.6 degree, Fz= 9 degrees
c) No clue.
Please correct me if I am wrong.

1. shouldn't the angle be 330deg?
on the force magnitudes, the unit is Newtons
f=fx i + fy j + fz k
fx=0, fy, fz as above
