How can you measure speed of a plane from the ground?

AI Thread Summary
To measure the speed of a plane from the ground, one can use methods such as radar, GPS tracking, or visual estimation combined with time measurements. The basic equation for speed is distance divided by time. For instance, if the distance a plane travels is known, and the time taken is measured, speed can be calculated easily. Radar systems provide precise speed measurements by calculating the Doppler effect of the plane's movement. Understanding the principles of motion and the tools available is essential for accurate speed measurement.

how can you measure the speed of the plane from the ground.

Can anyone help and please explain as much as you can and if you can provide the equation/example that would be wonderful.?

Have you got any ideas at all? What do you know about speed so far; that is, what is required to measure speed?
 
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...
