Simple harmonic motion

  • #1
Could anybody temme what wuld happen to the time period and the amplitude of oscillations if a mass attaching to a ruler, lying horizontally on the table, is broken ...then what effect would this have on the amplitude and time period of oscillations?

I say that amplitude would increase because mass is inversely proportional to amplitude and time period would decrease since it is directly proportional to mass....
the two formulas i derived my answers are...

F = mr (omega)^2

and T^2 = 4 x pi^2 x m/k

Am I right?

If I have understood your question (my english is not so good).
Using energy arguments if the mass brakes in two halfs when the potential energy is max, the potential energy is the same for the half attached to the spring since it just depends on the position of the mass, so the amplitude would be the same.
