[b]1. Homework Statement : An artificial satellite revolves about the Earth at height H above the surface. If the radius of the Earth is R, calculate the orbital speed and the orbital period such that a person in the satellite will be weightless. Homework Equations The Attempt at a...

Homework Statement Consider both a cylinder of radius Rc and mass mc and a hoop of radius Rh and mass mh. If both are at top of a ramp of length L and at angle theta, what are the objects speeds at the bottom of the ramp Homework Equations The Attempt at a SolutionWell, I think...

Thank you so very much

Sorry. I didn't post what I had tried to do because I have no clue where to even start. I'm not looking for the answer, I just wanted some help.

Ok. So basically you multiply the three together? Sorry if I am slow.

Homework Statement A comet of mass 5x10^16 kg moves in an elliptical orbit around the sun, with the sun at one focus. At the perihelion, 10^6 m, the comet has a linear velocity of 1.5x10^7 m/s. Find the angular momentum of the comet with respect to a focus at the sun. Homework Equations...

Homework Statement What is the value of I for a circular hoop of mass M and Radius R about an axis that is tangent to the hoop and lies in the hoops plane? Homework Equations The Attempt at a Solution I=2 theta intergral from -R to R, z^2 square root of (R^2 - z^2)dz = theta pi...
