Homework Statement
If the mass of a horizontal mass-spring oscillator undergoing SHM is 0.5kg and the force constant is 20N/cm, what is the maximum restoring force of the oscillator? And what is the maximum acceleration? (Time period is 6s and amplitude of oscillation is 12cm)
Homework Equations
Acceleration (a) = -w^2(x) and a = -k(x/m)
The Attempt at a Solution
When I use the given information and plug in the values, the answer is different for each equation. For the first equation, I get an answer of 0.13ms^-2, and for the latter I get 480ms^-2.
I don't seem to understand why they don't match and which one is correct. because I know we had to equate ma=-kx to derive the equation omega(w) = sqr.rt(k/m).
Any replies would be tremendously helpful. Thanks.
