2. Let’s Try This One Together
Vector is in the direction 34.0° clockwise from the –y axis. The x-component of is
= m.
What is the y-component of ?
What is the magnitude of ?

3. Let’s Try This One Together Too
A postal employee drives a delivery truck over the route shown in the Figure. Use the method of components to determine the magnitude and direction of her resultant travels

4. For Your Enjoyment… The magnitudes of two vectors and are
A = 12 units and B = 8 units. Which of the following pairs of numbers represents the largest and smallest possible values for the magnitude of the resultant vector =
(a) 14.4 units, 4 units
(b) 12 units, 8 units
(c) 20 units, 4 units
(d) none of these answers

5. Also For Your Enjoyment…
If vector is added to vector , under what condition does the resultant vector
have magnitude A + B?
(a) and are parallel and in the same direction.
(b) and are parallel and in opposite directions.
(c) and are perpendicular
