    Blackhole
AI Thread Summary
Two spaceships are approaching a black hole, with one traveling at 0.995C and the other at -0.03C relative to the first. The challenge is to determine if the first spaceship can stop the second from entering the black hole, given their relative speeds. The discussion reveals confusion regarding the second spaceship's position and the calculations needed to assess the situation. Despite attempts to analyze the problem, the conclusion leans towards the belief that stopping the second spaceship is not feasible. The complexities of relativistic speeds and distances complicate the scenario significantly.

Homework Statement


From our perspective a spaceship is traveling towards a black hole 9 light minutes away at 0.995C, another spaceship is traveling towards the black hole, traveling at a -0.03c from the point of view of the first spaceship. is it possible for the first spaceship to stop the second going into the black hole?

Homework Equations


t'=γ(t-(v/(c^2)))
x'=γ(x-Vt)
I think...

The Attempt at a Solution


As I don't know the position of the second spaceship, i spent an hour trying to figure various speeds/distances from both points of view, but ended up not getting anywhere.

i don't understand your question. i would go with no though.
 

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...
