A record rotates on a turntable at 33 rpm.?

that is true for LP records (the large ones that held around 30-40 minutes of music)

there were also 45 RPM records that were smaller, and held one song per side.

before that, there were large records that also held one song per side, and played at 78 RPM.

First we calculate the period. Since 45 rpm = 0.75 revolutions/second . Thus the period of rotation is 1.33 seconds. Thus the speed will be. v= 2πr/T = 2π (10 cm)/ 1.33 sec = 47 cm/s

Rotational Motion | Gary Garber's Blog – The turntable of a record player rotates at 33.33rev/min and takes 20.0s to reach this speed from rest. Calculate: a) its angular acceleration, b) the number of revolutions it makes before reaching its final speed.Get an answer for 'An old-fashioned vinyl record rotates on a turntable at 33 1/3 rev/min. What is the linear speed at radius r? An old-fashioned vinyl record rotates on a turntable at 33 1/3 revDue to the listening time of around 22 minutes, 33 ⅓ RPM (12 inch) records are primarily used for LPs (Long Play Records) which house full albums split over 2 sides. 45 RPM (7 inch) records are smaller in size and cheaper to produce, and can house around 5 minutes per side.
