Asked by Nat
A disk rotates with constant angular acceleration. The initial angular speed of the disk is 2π rad/s. After the disk rotates through 17π radians, the angular speed is 18π rad/s.
(a) What is the magnitude of the angular acceleration?
answer in rad/s2
(b) How much time did it take for the disk to rotate through 17π radians?
answer in s
(c) What is the tangential acceleration of a point located at a distance of 3 cm from the center of the disk?
answer in m/s2

wf^2=wi^2 + 2 a d solve for a.
b. wf=wi+at solve for t
c. when, at the end? acceleration=wf^2 *radius
b. wf=wi+at solve for t
c. when, at the end? acceleration=wf^2 *radius
