Question

4. A string is wrapped about the rim of a small hoop with a radius 8.00 cm and a mass of 0.180 kg. The free end of the string is held fixed and the hoop is released from rest. After the hoop has descended 75.0 cm, calculate (a) the angular speed of the rotating hoop and (b) the speed of its centre.Please be as clear and detailed as possible. Please include any formulas and diagrams you use to solve the problem. Thank you!
