How Do You Calculate Frequency and Period for a Mass on a Spring?

AI Thread Summary
To calculate the frequency and period of a mass on a spring, the frequency (F) is determined by dividing the total number of vibrations by the total time, resulting in F = 25 vibrations / 50 seconds = 0.5 Hz. The period (T), which is the time for one complete vibration, is the reciprocal of frequency, so T = 1/F = 1/0.5 = 2 seconds. The user is confused about the formula for period involving the spring's length (L) and gravitational acceleration (g), which are necessary for further calculations. The key formulas are F = 1/T and T = 2π√(L/g). Understanding these concepts is essential for solving the problem accurately.

Waves and Sound Vibrations Question Urgent Please Help??

Homework Statement


A mass suspended from the end of a spring vibrates up and down 25 times in 50s. What ar ethe frequency and period of the vibration.


Homework Equations


F = 1/T
T = 2(pie)3.14(squrroot)L/g


The Attempt at a Solution


F = 1/T
or is it:
F = 50/25
F = 2Hz?

T = 2(3.14)(sqrroot) but what is the L?

I'm very confused and I need to finish this soon!:confused::frown::cry:

Frequency = number of vibrations per second.
Period T = time for one vibration = 1/f
 

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...
