Questions 1 and 2: Find the components of these vectors:
1. (30.60 m x + 9.356 m y)
32 m/s
17^{o}
A = A = x + y
2. (5.861 m x + -13.81 m y)
23^{o}
B = B = x + y
15 m/s
Questions 1 and 2 are to see if you can find components of vectors. This is covered here:
3. Convert this vector component vector to an angle magnitude vector. Draw it as an arrow, and label any angle it makes with its value, and find the magnitude. (angle x: 23.4^{o}, mag: 14.4 m/s + picture)
C = 13.2 m/s x + 5.70 m/s y
Question 3 is to see if you can draw angle magnitude vectors from vector component vectors, and calculate an angle and the magnitude. This is covered here:
Powerpoint lesson on Vector Components to Angle Magnitude - be sure that you can draw it correctly
4. D = 16.2m x + -3.5 m y
E = -13.7m x + -4.2 m y Find:
D+E = x + y
2.5 |
-7.7 |
-29.9 |
-0.7 |
E-D = x + y
Question 4 is to see if you can add two vector component vectors. This is covered here:
5. Calculate the sum of vectors A and B (From problem 1 and 2). Draw the resultant vector as an angle magnitude vector. (Label your angle and magnitude clearly – use an arrow) Do your work on the back of this sheet, and label and describe the three steps for doing so. (36.9 m/s, 6.96^{o} below x axis +picture)
Question 5 is to see if you can add two angle magnitude vectors. This is covered here:
