Finding the Distance Fallen and Frequency Shift with Doppler's Effect

AI Thread Summary
The discussion focuses on solving a physics problem involving the Doppler Effect and a tuning fork falling from rest. The observer calculates the observed frequency of 487 Hz using the formula for the Doppler Effect, resulting in a calculated speed of 19.01 m/s for the tuning fork. The next step involves using motion equations to determine the distance fallen by the tuning fork to reach that speed. Participants suggest finding the fall time first to facilitate the calculation of the distance fallen. The conversation emphasizes the importance of applying motion formulas to complete the solution.

Dopplers Effect, Please Help!

Homework Statement



A tuning fork vibrating at 514 Hz falls from rest and accelerates at 9.80 m/s2. How far below the point of release is the tuning fork when waves of frequency of 487 Hz reach the release point? (Take the speed of sound in air to be 343 m/s.)

Homework Equations





The Attempt at a Solution



fobs=[1/((1+u)/343)]*fsource

487=[1/((1+u)/343)]*514
u=19.01 m/s

That's as far as I got. I'm not sure what to do next or if I'm even on the right track. Any help would be appreciated. Thanks

The formula looks a little odd, but I think the 19 m/s is correct.
Next step is to use motion formulas to find out how far it has fallen to acquire that speed. You might want to find the fall time first.
 

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...
