What is the speed of the dot

Reference no: EM13705403

Problem: A computer hard disk 8.0 cm in diameter is initially at rest. A small dot is painted on the edge of the disk. The disk accelerates at 680rad/s² for 12s, then coasts at a steady angular velocity for another 12s.

Part A: What is the speed of the dot at t = 1.0 s?

I need help to determine the speed of the dot.
