    Friction less Banked curve

    Well here is a neat link on the forces at work on a banked curve:http://hyperphysics.phy-astr.gsu.edu/hbase/mechanics/carbank.html But it does include friction but it will at least give you a really good idea as to what exactly is at play here. Hope it helps.

    Simple question about projectile motion

    You are right though that any angle is valid. Though pi/4 is the most efficient choice.

    Simple question about projectile motion

    I guess you could say that but the path and final velocity would be different for each angle. The problems I have always dealt with specify how to pick the angle, but if we are neglecting air drag and the curvature of the earth then 45 degrees would be probably be the best angle to chose.

    A different kind of solar power

    Im not sure about the efficiency of these but it sounds very similar to what you are describing. http://www.renewableenergyaccess.com/rea/news/story?id=44696 [Broken]

    Car Aerodynamics: Experimental trials not agreeing with lift theory, help

    Nevermind, carl your right I retract my statement I was thinking the oppossite. But then why would the tests show differently.

    Car Aerodynamics: Experimental trials not agreeing with lift theory, help

    I am by far not qualified to really answer this but just from thinking about it. Wouldnt the air deformed by the front of the car move downward to fill the area of lower pressure between the roof and trunk on the rear of the car. Thus creating a downward force on the car which I assume would be...
