The record turns on a turntable that rotates at variable speed. The coefficient of static friction between the coin and the record is 0.30. A turntable reaches an angular speed of 33.3 rpm, in 2.0 s, starting from rest. (a) Assuming the angular acceleration is constant, what is its magnitude? (b) How..."… is made to rotate on the turntable at constant speed, usually 33.3, 45, or 78 revolutions per minute (rpm)."

As the record rotates one time, it rotates an angle of 2 π radians. One minute is 60 seconds. 1 rpm = 2 π/60 = π/30 rad/s. The period is the time for the record to rotate one time.A 45 rpm adapter (also 45 rpm record insert, 45 rpm spindle adapter, or 7 inch adapter, the common size of 45 RPM records) is a small plastic or metal insert that goes in the middle of a 45-rpm record so it can be played on the standard size spindle of a turntable.The major advantage that 45 RPM records brought to the table was again one of size.

What are (a) the angular velocity in rad/s and (b) the period of the motion? Show transcribed image text A turntable must spin at 33.3 rpm to play an old-fashioned vinyl record.

As the record rotates one time, it rotates an attitude of two π radians. One minute is 60 seconds.

1 rpm = 2 π/60 = π/30 rad/s

ω = 45 * π/30 = 1.5 * π rad/s

The duration is the time for the record to rotate one time. To decide the time, use the following equation.

θ = ω * t

θ = 2 π

2 π = 1.5 * π * t

t = 2/1.5 = 1⅓ seconds

I am hoping this lets you understand how to solve this type of problem
