A thin, 108 g disk with a diameter of 8.5 cm rotates about an axis through its center with 0.25 J of kinetic energy. What is the speed of a point on the rim?
Question
Solution 1
Sure, here are the steps to solve this problem:
First, we need to calculate the moment of inertia (I) of the disk. The formula for the moment of inertia of a disk rotating about an axis through its center is I = 0.5mr^2, where m is the mass and r is the radius.
Given that the mass m = 108 Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
