To Find: The linear speed of a point on the circumference of the disc
Answer to Problem 39RE
Explanation of Solution
Given information: The radius of a compact disc is
Concept used: Consider a particle moving at a constant speed along a circular arc of radius r. If s is the length of the arc travelled in time t, then the linear speed v of the particle is
Calculation:
The radius of a compact disc is
And disc is rotating at a speed of
Because each revolution generates
It follows that the wheel turn
The linear speed is
