In this displacement (m) versus time (s) graph, we can see that the recorded object has a velocity of ________?

• 1.25 m/s

• .75 m/s

• .5 m

• .5 m/s

Vector A = 3.00i -  $3.00\sqrt{2.00}$ j,  what is vector A in magnitude angle notation?

• 4.23 @  $30^o$  

• 6.00 @  $30^o$  

• 6.00 @  $330^o$  

• 4.23 @  $330^o$  

How is velocity related to displacement?

• It is the slope of the displacement graph

• It is the average of the displacement graph

• They aren't

• They're second cousins

How do you feel right now?

• I got everything right

• I got most of the answers right

• I didn't get most of the answers right and should schedule extra help

• I'm just here so I don't get fined
