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. Homework Equations The...

It says it is not the right answer though. That is why I am confused.

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 =...

Homework Statement A person grabs on to an already spinning merry-go-round. The person is initially at rest and has a mass of 29.5 kg. They grab and cling to a bar that is 1.70 m from the center of the merry-go-round, causing the angular velocity of the merry-go-round to abruptly drop from...

Homework Statement A uniform thin rod with mass 4.59 kilograms pivots about an axis through its center and perpendicular to its length. Two small bodies with a mass of 0.543 kilograms, are attached to the ends of the rod. What is the length of the rod such that the moment of inertia of the...
