The helicopter view in Fig. P3.15 shows two people pulling on a stubborn mule. The person on the right pulls with a force F1 of magnitude 120 X and direction of 1 = 60.0. The person on the left pulls with a force F2 of magnitude 80.0 N and direction of 2 = 75.0. Find (a) the single force that is equivalent to the two forces shown and (b) the force that a third person would have to exert on the mule to make the resultant force equal to zero. The forces are measured in units of newtons (symbolized N). Figure P3.15
(a) Find the magnitudes of the forces F1 and F2 that add to give the total force Ftot shown in Figure 4.35. This may be done either graphically or by using trigonometry. (b) Show graphically that the same total force is obtained independent of the order of addition of F1 and F2. (c) Find the direction and magnitude of some other pair of vectors that add to give Ftot. Draw these to scale on the same drawing used in part (b) or a similar picture.

In a tug-of-war game on one campus, 15 students pull on a rope at both ends in an effort to displace the central knot to one side or the other. Two students pull with force 196 N each to the light, four students pull with force 98 N each to the left, five students pull with force 62 N each to the left, three students pull with force 150 N each to the right, and one student pulls with force 250 N to the left. Assuming the positive direction to the tight, express the net pull on the knot in terms of the unit vector. How big is the net pull on the knot? In what direction?

While sliding a couch across a floor, Hannah and Andrea exerts forces F⃗HF→H and F⃗AF→A on the couch. Hannah's force is due north with a magnitude of FH = 141 N and Andrea's force is θ = 26° east of north with a magnitude of FA = 241 N. In this problem, use a coordinate system with y directed north and x directed east. 1. Find the net force in the y-direction in Newtons. 2. Calculate the angle in degrees north of east of the net force exerted on the couch by Hannah and Andrea, F⃗HAF→HA. 3. Hannah and Andrea's housemates, David and Stephanie disagree with the move and want to prevent its relocation. Their combined force F⃗DSF→DS must be equal and opposite to that of F⃗HAF→HA. What is the magnitude in Newtons of the force F⃗DSF→DS which will prevent the relocation? 4. Find the net force in the x-direction in Newtons.
