Question

find the angular velocity in radians per minute and linear velocity in inches per minute for a point on the edge of a 6.9 - in. - diameter record spinning at 44 rev/min. the angular velocity is radians per minute. (simplify your answer. type an integer or decimal rounded to the nearest tenth.)

Explanation:

Step1: Recall the formula for angular velocity

Angular velocity \(\omega\) (in radians per minute) is given by \(\omega = 2\pi n\), where \(n\) is the number of revolutions per minute.

Step2: Substitute the value of \(n\)

Given \(n = 44\) rev/min. Then \(\omega=2\pi\times44\).
