first off, thanks for all the help. My physics book got taken when my car got broken into and my backpack was taken. I have an old book and my pages don't coencide with my homework. everyone has been a big help. with that,, i just have two final questions about centripetal force:
1. A ventilation fan has blades 0.25 m long rotating at 2 rad/s.
What is the centripetal
acceleration of a point on the outer tip of a blade?
2. An airplane is a wide sweeping "outside" loop can create zero "g"
(weightlessness) inside
the aircraft cabin. What must be the radius of curvature of the
flight path for an aircraft
moving at 70 m/s to create a condition of "weightlessness" inside
the aircraft?
Im really not sure where to start with these, although I do realize that I need to account for gravity, just not sure what kind of equation I am looking for.
