AI Thread Summary
The discussion centers on estimating the speed of an object seen in a video at around 1:51, which could be a jet, bird, or UFO. Participants note that without knowing the distance from the camera, accurately determining the speed is challenging. One estimate suggests the object could be traveling around 600 mph, but this remains speculative. The difficulty lies in identifying the object's size and speed based on the camera's angle and perspective. Ultimately, the conversation highlights the limitations of making precise speed assessments without additional data.

Homework Statement


I want to know how fast this jet, bird, UFO is traveling at around 1:51. It appears to the right of Dana's head in the interview.

The Attempt at a Solution


Around 600 mph?

It is too hard to find out its speed without knowing distance from camera, if it is a jet, you *may* guess its size and speed may be obtained with cameras view angle, but it is too hard to find. There may only be guesses i think.
 
Estimations are what I'm looking for anyways, I just want someone to either rule out a bird.
 

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...
