SUMMARY
The angular displacement of a CD with a radius of 6.0 cm rotating at an angular velocity of 5.0 rad/s over a time period of 2.0 seconds is calculated to be 10 radians. The formula used is Delta θ = ωt, where ω is the angular velocity and t is the time. The radial acceleration is not relevant in this scenario as the radius remains constant. Consequently, a point on the circumference of the CD travels a linear distance of 60 cm during this time.
