I just wanna know what it would approximately look like in a and b

Question: When an object is pushed several ways at once, what is the net effect? In mechanics, we think of "force" as a push or a pull. A scientific definition will be discussed later in lecture, and the effects that forces produce on motion will be a major topic of this co unit of force in the SI system is the Newton (abbreviation N). For purpo be concerned with the way that different forces combine to produce at urse. The ses of this exercise, we will otal force. Part P-1: North Force of wind on sai Example -A sailboat in a lake is pushed northeast by the wind and east by the lake current, as in Figure 1. These forces are indicated in the figure with arrows. The total force on the boat will be directed somewhere between these two. In fact, we can find exactly what is the effect of the combined forces by a technique shown in Figure 2. East Force of current on boat Figure 1: Two forces on a sailboat: Note that the two forces are drawn from a common point. In Figure 2 we have drawn a parallelogram whose sides are parallel to the two forces. The diagonal of this parallelogram (drawn from the same common point) is the total force acting on the boat. The length of the vector represents the total amount of force (magnitude) on the boat and the direction the vector points is the direction of that total force. Whenever two forces act on the same object, the total force can be found this way. The total force is sometimes called the resultant of the other two. Using a ruler and a protractor draw a vector diagram, like the one shown in Figure 2. Figure 2 will help you find the resultant force on the boat by the parallelogram method total force on boat For this problem use the following information: now the wind pushes the boat with a force of 500N at an angle of 60° north of east while the current pushes the boat with a force of 300N at an angle of 45° south of east. Figure 2: Finding the total force on the sailboat by the parallelogram method. First pick a scale for the length of the vectors to adequately represent the forces given. Your scale should be set up so that the vector diagram takes up most of the graph paper. Be sure to write your scale (with units!) on the diagram and label the vectors.
