Lab Day & Time: Physics 1080 Forces and Traction: Prelab 50 2 Part 1 100 1. You are standing outside your house and walk 100m north. You turn right and walk 50m east. Finally, you turn right again and walk 100m south. a. How far have you walked? b. How far are you from your starting point in the north/south direction? c. How far are you from your starting point in the eas/west direction? d. How far are you from your starting point, overall? When one component of a vector is zero, finding the resultant requires no additional steps. When this is not the case, finding the total vector magnitude is a bit more complicated. After the route taken in question 1, you walk an additional 100m south. 2. a. How far are you from your starting point in the north/south direction? b. How far are you from your starting point in the east/west direction? 1 of 12 Forces and Traction Date modified: 8/8/2017
Draw these component vectors head-to-tail, so that one vector starts where the other ends. Connect the start of the first vector to the end of the second, as shown in Figure 1. Include the Scale you used. c. Vector 2 Vector 1 Figure I: Adding vectors d. The Pythagorean Theorem relates the lengths of the three sides of a right triangle (see Figure 2). Use the Pythagorean Theorem to find the length of the resultant vector you constructed in part 0. Make sure to include units with your answer. eis across from the right angle. Pythagorean Theorem: a2 + b2-C2 Figure 2: The Pythagorean theorem Beside a magnitude, a vector needs a direction. The angle made between a vector and the horizontal is found using triangle relations (see Figure 3). Find the angle made between your vector from part 0 and the horizontal. e. tan@)s- ー→ 6-tan-ı ( Figure 3: The angle
Part 2 3. Just as a vector can be made from components, a vector can be split into components. This is done using similar triangles, which are triangles that have the same shape, but different sizes (see Figure 4). This allows you to find the lengths two sides of a triangle if the length of the third side is known. a. Triangles A and B in Figure 4 are similar. Find the lengths of the sides of triangle B. How did you do this? Justify your method. B. igare 4: Similar triangles b. Triangles A and B in Figure 5 are similar. Find the lengths of the sides of triangle B. Did you use the same method as in the previous question? 4 em cm 0.8 cm 0-53 0.6 cm Figure S: Similar triangles, revisited 4. In the second part of question 3, your reference triangle had a diagonal (hypotenuse) with a length of 1. When this is the case, the sides of the triangle can be given using trigonometric functions. The side of the triangle that touches the angle is represented by the cosine of that angle, and the side across from the angle is represented by the sine of the angle (see Figure 6). Note that all that is necessary for the triangles A and B (in Figure 5) to be similar, is that the given angle is the same. Find the sine and cosine of the angle given in Figure 6. Are these values consistent with the reference triangle you were using? a. 1 cm Sİn@ Figure 6: Reference triangle Forces and Traction 3 of 12 Date modified: 8/8/2017
b. From the triangle in Figure 7, draw a reference triangle with a hypotenuse of 1 cm Label all lengths, and show how you found each length. 15 cm 37 Figure 7: A right triangle c. Now find the lengths of the missing sides in the triangle in Figure 7. Show your work. 5, In this lab, you will be making extensive use of Excel.

  • To use trigonometric functions to find sides and angles of right triangles.

    Learning Goal:To use trigonometric functions to find sides and angles of right triangles.The functions sine, cosine, and tangent are called trigonometric functions (often shortened to "trig functions"). Trigonometric just means "measuring triangles." These functions are called trigonometric because they are used to find the lengths of sides or the measures of angles for right triangles. They can be used, with some effort, to find measures of any triangle, but in this problem we will focus on right triangles. Right triangles...

How far are you from your starting point, and what is the compass direction of a line connecting your starting point to your final position? (If you represent the two legs of the walk vector displacements A and B, as in Figure 3.56, then this problem finds their sum R = A + B.)

How far are you from your starting point in meters?" Originally, I had tried using pythagorean theorem where a was 12 and b was 20, but that was incorrect I am assuming because the triangle is not a right triangle. I then tried the second method underneath the...
