    Deriving an expression for the radius of a satellite's orbit around Earth(?)

    Homework Statement Derive an expression for the radius of a satellite's orbit around Earth in terms of the period of revolution, the universal gravitation constant, and Earth's mass. Homework Equations The final equation should be: r = \sqrt[3]{\frac{T^{2}Gm_{E}}{4\prod^{2}}} The...

    Projectile Motion Problem and Muzzle Velocity Help Needed

    Thanks, I think I will try it this way! I may have made everything too complicated for myself by isolating v before plugging in the numbers. In order to get remove the half from g, and the square from cos, is that because you were able to cancel them out from each other? Great, then I know...

    Projectile Motion Problem and Muzzle Velocity Help Needed

    Homework Statement A cannon is discharged towards a castle tower (near the time when the ancient world was meeting the modern world). The cannon ball flies 5 m above the top of the 10 metre tall tower and lands on level ground (same level as cannon) behind the tower. The cannon was...

    Graduate Question about the edge of the Universe

    Okay, I think I understand that. So it's akin to walking around the earth, trying to find the edge. No matter how far you walk, you will just end up right back where you started. Is this what you would say? Funny thing is, I've actually said this before. I've also made reference to Futurama by...

    Graduate Question about the edge of the Universe

    So does this mean the universe is almost like a sphere of space, of nothingess? And we are just matter suspended in said nothingness? But if it is such, then what is outside this finite space? What holds the universe together? What would happen if we were to transcend this finite space?

    Projectile Motion Equation Need Help Re-arranging Please

    Aaah, thank you very much for the reply! And yes, I am familiar with the Quadratic Formula, but haven't used it in a year. I made the mistake of stopping math at Grade 11 U level, in the same semester as my Grade 11 U Physics, and then taking Grade 12 U Physics, after having no math for a year...

    Projectile Motion Equation Need Help Re-arranging Please

    Hey, this is my first time posting here, I just found this site in a Google search. I've been doing a projectile motion question, and I know what I am doing and solving for and such, but I am having great difficulties re-arranging the equation I need. The equation looks like so: \Deltad_{}y =...
