How do you determine the horizontal component of a 30 m/s vector at 110 degrees?

30 sin 110

30 cos 110

110 sin 30

110 cos 30

The vector diagram above represents the horizontal component, F_H, and the vertical component, F_V, of a 24-newton force acting at 35⁰ above the horizontal. What are the magnitudes of the horizontal and vertical components?

F_H = 20 N and F_V = 14 N

F_H = 4.9 N and F_V = 3.5 N

F_H = 3.5 N and F_V = 4.9 N

F_H = 14 N and F_V = 20 N

15.

Remember, do a diagram if you think it will help:

A body is acted on by a vertical force of 18 N and a horizontal force of 32 N.

The angle to the horizontal of the resultant force is given by

$\cos^{-1}\left(\frac{18}{32}\right)$

$\tan^{-1}\left(\frac{18}{32}\right)$

$\sin^{-1}\left(\frac{32}{18}\right)$

$\tan^{-1}\left(\frac{32}{18}\right)$
