Determine the Net Force acting on the object (represented by the solid circle) in this diagram.
wlad13 [49]

Answer:

200 N to the left

Explanation:

If we say left is negative and right is positive, then the net force is:

∑F = -300 N + 100 N

∑F = -200 N

The net force is 200 N to the left.

Find the resultant of two forces of 4.0N and 6.0N acting at an angle of 160° to each other.
hichkok12 [17]

\star\sf \overrightarrow{A}=4N

\star\sf\overrightarrow{B}=6N

Angle=160

\boxed{\sf R=\sqrt{A^2+B^2+2ABcos\theta}}

\\ \sf\longmapsto R=\sqrt{4^2+6^2+2(4)(6)cos160}

\\ \sf\longmapsto R=\sqrt{16+36+48(-0.93)}

\\ \sf\longmapsto R=\sqrt{52-44.6}

\\ \sf\longmapsto R=\sqrt{7.4}

\\ \sf\longmapsto R=2.7N
