SUMMARY
The period of oscillation for a hoop with a radius of 0.18m and mass of 0.44kg, suspended by a point on its perimeter, is calculated to be approximately 0.602 seconds. The moment of inertia (I) is determined using the formula I = 2(MR^2), resulting in I = 0.028512 kg·m². The relationship between potential energy and rotational kinetic energy is applied, leading to the calculation of angular velocity (w) and subsequently the period (T) using the formula T = (2π)/w.
