Questions 1 and 2: Find the components of these vectors:

1. (30.60 m x + 9.356 m y)

32 m/s

 

17o

A = A = x + y

 

 

2. (5.861 m x + -13.81 m y)

 

 


23o

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: 23.4o, 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:

 

 

 

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, 6.96o below x axis +picture)

 

 

Question 5 is to see if you can add two angle magnitude vectors.  This is covered here:
