2. A rigid disk with radius 2 m is spinning at an angular speedof 8 1/s (or 8 rad/s). A constant angular acceleration is appliedthat slows downthe disk at a rate of 2 1/s2(or2 rad/s2).
(i) Calculate the number of revolutions the disk does beforecoming to a full stop.
(ii) Calculate the centripetal acceleration of a point,positioned at 1 m from the disk rotation axis, at t = 2 s.
(iii) Calculate the tangent speed of a point positioned at theedge of the disk at t = 2 s.
