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.
+600 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!)
