**Instructions: Draw a
picture, show all work (including initial equation). Please box answers and
include units in your answers for full credit.**

** **

**1) ****Find the polar coordinates of a triangle with x
component 8 m/sec and a y component of 7.5 m/sec.**

** **

** **

**R
= 10.97 m/sec**

**q**** = 43.15 degrees**

** **

** **

**2) ****What are the rectangular coordinates of a triangle
with rectangular coordinates of (35, 67)?**

** **

**Y
= 32.22**

**X
= 13.68**

** **

** **

**3) ****Define scalar and vector and give an example of
each.**

** **

**Scalar
has only magnitude. Mass**

**Vector
has magnitude and direction. Acceleration**

** **

** **

**4) ****what is the displacement of a vector that travels
from (3,5) to (23,22) ?**

** **

** X = 23-3 = 20**

** Y = 22-5 = 17**

** **

** **

**5) ****What are the resultant vector and angle of the
displacement?**

** **

**R
= 26.56 **

**q**** = 40.36 degrees**
