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
