Speed Relative to an Observer on the Ground

AI Thread Summary
The discussion focuses on calculating the speed of a shuttle orbiting Earth relative to an observer on the ground. The shuttle's velocity is given as 7.7x10^3 m/sec, with the distance to the observer being 6.7x10^6 m. One participant expresses confusion about determining the relative speed and suggests translating the shuttle's speed to angular velocity for better understanding. They propose considering the observer's neck as a pivot point to calculate the rotational speed at a specific distance from that point. The conversation emphasizes the need for clarity in approaching the problem to find the correct answer.

Homework Statement



A shuttle is orbitting around the Earth at a velocity of (7.7x10^3) m/sec. The distance between a point on the Earth to the shuttle is (6.7x10^6)m. Calculate the speed of the shuttle relative to an observer on the earth.


Completely lost! I was able to solve the question before it, but I can't find a way to determine the speed. If you need more informatio or if I left anything out, tell me.

Just a thought, this is what I would do, but do not take this as an answer, weight for the real clever guys to come and give an opinion.
Translate the speed of the shuttle to angular velocity. This will give a different speed at different radiu'... If you take the observers neck as its turning point and his eyes is 100mm from the rotation point, what would the speed be at which his eyes will be rotating about his neck, this will be the relative speed to the observer... This is just a thaught and how I will approach this, cheers! Hope you find the answer...
 

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 '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...
