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
