Please help:)
A mass less spring hanging vertically, extends by 5cm when a mass M is attached to its lower and vertical oscillations are started by pulling the mass M downwards by another 5cm and then releasing it.
i.Find the frequency of oscillation and the maximum velocity of the oscillating mass.
ii.If a second mass of 300g is added to M the frequency of oscillation is reduced to half the previous value. Find M.

Best ResponseYou've already chosen the best response.02pi comes only when we find f right?

Best ResponseYou've already chosen the best response.0oh. you're not using \(v=\frac{2\pi}{T}\) the answers are different though...

Best ResponseYou've already chosen the best response.0sorry. but \(\omega\) is only equal to (\frac{2\pi}{T}\). Isn't t? Maximum velocity is \(A\omega\)

Best ResponseYou've already chosen the best response.0oh right. sorry. a lil rusty in SHM. right. v=rw so your answer's right.

Best ResponseYou've already chosen the best response.0i too am a little rusty on SHM but isn't the frequency of oscillation independent of the mass attached to the spring?

Best ResponseYou've already chosen the best response.0wouldn't \(\omega' \)also change because of the increase in mass by 0.3g? @rajathsbhat that is for simple pendulum.

Best ResponseYou've already chosen the best response.0it will be \(\omega'=\omega/2\).

Best ResponseYou've already chosen the best response.0in g? not in SI units? lol though there wouldn't be much difference anyways. except for the mass part, i think it's okay.
