rmly for t -20 s to a final ugh its center. Make sure your answers are in SI units. th mass m 10kg and radius R- 0.5 m begins at rest and accelerates angular speed of ω 60 revs/sec. It rotates about an axis MR hat is the angular acceleration of the disk during this time period? t : 入。 hrough what angular displacement has the disk moved through at -20s? Represent your answer in termsof ans, degrees, and revolutions. Vhat is the total distance a point at the edge of the disk has travelled through during the 20s? 2기 What are the centripetal and tangential components of the acceleration at a point R/2 from the axis of rotation m/s 20s? What is the speed at the edge of the disk at t t 20s, a brake is applied to the disk such that it slows down and comes to rest. While it slows down, a point edge travels through a distance of 20 m. How long does it take the disk to slow down?
