Question

il AT&T; 12:27 PM 40%)10 a edugen.wileyplus.com WileyPLUS Chapter 01, Problem 31 Your answer is partially correct. Try again. A car is being pulled out of the mud by two forces that are applied by the ae two ropes shown in the drawing. The dashed line in the drawing bisects Cethe 30.0 angle. The magnitude of the force applied by each rope is 2900 ae1 stnewtons (N). (a) How much force would a single rope need to apply to accomplish the same effect as the two forces added together? (b) What angle would the single rope make relative to the dashed line

Explanation / Answer

Angle between 2 ropes is 30°. That means you have to consider 15°

The magnitude of the force applied by 1 rope is 2900 newtons.

2900N * cos15° = 2800 N

Two ropes: 2800 * 2 = 5600 N (Answer a)
and angle = 15 degrees (Answer b)
