**Rotational Motion of an LP Record****Part A: Calculating the Frequency of Rotation**---**Problem Statement:**An old-fashioned LP record rotates at 33 1/3 rpm.**Question:**What is its frequency in rev/s?Express your answer in revolutions per second.---**Explanation:**The problem involves calculating the rotational frequency of an LP record given its rotational speed in revolutions per minute (rpm). The frequency is denoted in rev/s.**Steps to Solve:**1. **Identify the given value:** - Rotational speed (ω): 33 1/3 rpm2. **Convert rpm to rev/s:** - 1 rpm = 1/60 rev/s3. **Apply the conversion:** - (33 1/3) rpm = (100/3) rpm - Therefore, (100/3) rpm * (1/60) rev/s = (100/3) * (1/60) rev/s - Simplify the multiplication: (100/180) rev/s = (5/9) rev/s**Answer:** Therefore, the frequency of the LP record is **5/9 rev/s**.**Note:**Understanding the conversion from minutes to seconds is crucial for this calculation, as it ensures that the units are consistent for accurate computation. ---This problem demonstrates the principles of rotational motion and unit conversion, which are fundamental topics in physics.

Let's begin with the angular acceleration of a compact disk (CD). To play music the CD must rotate at high speed while a laser reads data encoded in a spiral pattern on the disk. The disc has radius R = 6.0 cm = 0.060 m; when data are being read, it spins at 7200 rev/min. What is the CD's angular velocity w in radians per second? How much time is required for it to rotate through 90° ? If it starts from rest and reaches full speed in 4.0 s, what is its average angular acceleration?
