1)   A mouse is walking along a ruler, if it begins at the location x = 5cm, and then does the following: - It walks to x = 12cm - It then walks -8cm - Lastly, it walks to the location x = 7cm. What is its velocity if it takes 10 sec to complete the motion?

 

2) Find the average velocity (in m/s) of a bicycler that starts 150 meters north of town and is 1200 meters north of town after 30.0 minutes.

1) Velocity is not speed. The mouse only went 2cm forward, that's it. His velocity is them 2cm/10 sec = 1/5 cm/s

 

2) Distance is 1200-150=1050 meters. So v=1050/(30*60)=7/12 m/s (Incredibly slow!)
