(a) Find Michelle's Average speed. 
(b) Find Michelle's average velocity. 
----------------------------------
Answers: 
(a) Find Michelle's average speed.
6+0+6/ 8 = 12/8 = 3/2 m/sec
Michelle's average speed was 3/2 m/s.

(b) Find Michelle's average velocity. 
0/8 = 0 m/sec
Michelle's average velocity was 0 m/sec. ]]> 2018-10-25 19:10:54 UTC https://padlet.com/emilanovich1/qbaqcqhhx61e/wish/297144869 7.

Realizing he forgot his dog Davinci at home, Jeffree turns around going northbound and reaches a speed of 20 m/s at 20 seconds. What is Jeffree’s average acceleration?
---------------------------
find the slope of the secant line
points: (0, -10) and (20,20)
