Question
In Exercises $17-58,$ solve the given problems.A DVD has a diameter of 4.75 in. and rotates at 360.0 r/min. What is the linear velocity of a point on the outer edge?
Step 1
75 inches. We need to find the radius of the DVD, which is half of the diameter. So, we divide the diameter by 2 to get the radius. \[r = \frac{D}{2} = \frac{4.75}{2} = 2.375 \text{ inches}\] Show more…

In Exercises $17-58,$ solve the given problems. Most DVD players use constant linear velocity. This means that the angular velocity of the disk continually changes, but the linear velocity of the point being read by the laser remains the same. If a DVD rotates at 1590 r/min for a point $2.25 \mathrm{cm}$ from the center, find the number of revolutions per minute for a point $5.51 \mathrm{cm}$ from the center.
In Exercises $17-58,$ solve the given problems. A helicopter blade is $2.75 \mathrm{m}$ long and is rotating at $420 \mathrm{r} / \mathrm{min}$. What is the linear velocity of the tip of the blade?
