in his backyard at Richmond? It just occurred to me that Kyle Busch will be racing in Virgina this weekend. I sure hope that KIA has been practicing his 12 ounce malted beverage throwing techniques.
I am designing a sailing boat for some course work and want to know how the position of the mast changes things like pointing angle and speed, if anyone does know.
Thanks

Interesting question for those who are interested (and have the know-how, which I lack). The question is as follows: How long would it take a square solar sail 10ft on every side and an undetermined mass (m) to travel from Earth to Alpha Centauri (4.134838 x 10^16 m away (1.34 parsecs))...
Taking photos from a digital camera attached to a balloon, floating 20m in the air could get you into a lot of trouble. You could get it wrapped around a power line, for example. Or injure a low-flying bird. More »

boat's sails. This force is d? As a sailboat sails 55.5 m due north, a breeze exerts a constant force F1 on the boat's sails. This force is directed at an angle west of due north. A force F2 of the same magnitude directed due north would do the same amount of work on the sailboat over a distance...
A new spacecraft is being launched in about a year, one designed to travel across the solar system. But instead of using rockets to propel itself, it uses sails. Sails pushed by light.
Starlight carries not only energy but momentum. Comet tails, for example, are the result of light blowing...
