AI Thread Summary
The discussion focuses on calculating the orbital parameters of the Space Shuttle, which orbits at an average altitude of 210 miles and has a mass of approximately 100,000 kg. Key questions include determining the distance from the center of the Earth, calculating the required orbital velocity using force equations, and understanding the behavior of potential and kinetic energy during an orbit. Participants encourage attempting the problems independently before seeking help, emphasizing the importance of grasping fundamental concepts. The conversation highlights the need for foundational knowledge in physics to tackle these calculations effectively. Overall, the thread aims to assist in understanding the principles of orbital mechanics related to the Space Shuttle.

Homework Statement


The orbit of the Space Shuttle is usually circular with an average altitude above the Earth of around 210 miles. The mass of the Space Shuttle on orbit is about 100,000 kg.

1. What is the distance of the Space Shuttle (shuttle) from the center of the Earth?
2. Using forces, calculate the velocity of the shuttle required to maintain a circular orbit.
3. How should the potential energy and kinetic energy behave throughout one orbit?

Homework Equations



K=1/2mv^2

U=-G(m1m2/r)

The Attempt at a Solution



I'm still struggling to grasp some of these concepts and wanted to get a head start with this stuff for the weekend. Anyone think they can get me started? Thanks

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
