Vectors

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:
