<em>F</em> = 153 N

\theta = 11.3°

Explanation:

Let us define first our directional convention. Anything pointing up or to the right is considered positive and anything pointing down or to the left is considered negative. Now let's look at the components F_{x} and F_{y}:

F_{x} = 350 N - 200 N = 150 N

F_{y} = 180 N - 150 N = 30 N

The magnitude of the resultant force <em>F</em> is given by

F = \sqrt{F_{x}^{2}+F_{y}^{2}}

\:\:\:\:\:\:= \sqrt{(150\:N)^{2}+(30\:N)^{2}}

\:\:\:\:\:\:=153\:N

To find the direction \theta, we use

\tan \theta = \dfrac{F_{y}}{F_{x}}=\dfrac{30\:N}{150\:N}=0.2

or

\theta = \tan^{-1}(0.2) = 11.3°

xxMikexx [17]

Answer:

Significant digits (also called significant figures or “sig figs” for short) indicate the precision of a measurement. A number with more significant digits is more precise. For example, 8.00 cm is more precise than 8.0 cm.
