Schach [20]

Answer:

Magnitude of the resultant force (Rf) = 923.5 N (Approx)

Step-by-step explanation:

Given:

Force f1 = 418 N

Force f2 = 590 N

Angle between the forces = 48°

Find:

Magnitude of the resultant force (Rf)

Computation:

Rf = \sqrt{f1^2+f2^2+2f1f2cos\theta} \\\\ Rf = \sqrt{418^2+590^2+2(418)(590)cos(48)}\\\ Rf = \sqrt{174,724+348,100+330,041.98} \\\\ Rf = \sqrt{852,865.98}\\\\ Rf = 923.5

Magnitude of the resultant force (Rf) = 923.5 N (Approx)

<span>Asking a student if they have violated the honor code is not the proper question to ask, for a couple of reasons. First is that maybe they don't even know what the honor code is, and second maybe the students aren't being honest in fear of the reprecussions.</span>
