Homework Statement
A 0.241-kg particle undergoes simple harmonic motion along the horizontal x-axis between the points x1 = -0.349 m and x2 = 0.419 m. The period of oscillation is 0.511 s. Find the frequency, f, the equilibrium position, xeq, the amplitude, A.

Forgot that . Here:
If L is conserved, then L(initial) = L(final), so L(final) = I(merry) * ω(initial).
So
I(merry) * ω(initial) = I(merry) * ω(final) + I(person) * ω(final). Solving for I(merry), shortened to I:
I * 45rpm = I * 19.0 + 82.255 * 19.0
45I = 19I + 1562.845
27I =...
