A circular disk of radius 0.010 m rotates with a constant angular speed of 5.0 rev/s. What is the acceleration of a point on the edge of the disk?
answer is 9.9 m/s ^2
My attempt:
The problem is asking me for the tangential acceleration of the disk.
At = rα
so to solve the above equation i need the value of α
the problem just gave me the velocity , so can i use that velocity in lie of acceleration? why not!?
