1. Banked Curves and Conical Pendulums

2. Steps to Solve (Draw a picture) Construct the FBD
Sketch the components of the appropriate force
Write both 2nd Law Equations
(SFy=may & SFc = mS2/r)
Substitute and Solve
(What did I forget???)

3. EX 1
At what angle (relative to horizontal) should an on-ramp be banked if it has a radius of 50m and drivers should be able to maintain a speed of 10 m/s without needing friction to negotiate the turn?

5. Example
p 144 #51

6. Lab - Objective: World Domination!!!

7. Objective:
Use a CONICAL PENDULUM to determine g (the acceleration due to gravity)
Derive an equation that will be of the form g= …
Determine what measurements must be taken
Present your findings to Dr. Evil! Mwuhahaha….MWUHAHAHAHA…hahahaha….
