AI Thread Summary

To calculate the constant acceleration needed for an airplane to stop from a southwest velocity of 59 m/s over a distance of 1.2 km, the equation d = (v_f^2 - v_i^2) / (2a) can be utilized. Here, v_f is the final velocity (0 m/s upon stopping), and v_i is the initial velocity (59 m/s). Rearranging the equation allows for solving acceleration (a) as a = (v_i^2) / (2d). Substituting the values gives the necessary acceleration to determine how quickly the airplane must decelerate. This approach effectively addresses the problem of calculating constant acceleration during landing.

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...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
