An Lp Record Rotates At 33 1/3 Rpm And Is 12 Inches In Diameter. What Is The Angular Velocity In

A record rotates at 33 1/3 revolutions per minute. Find the angular velocity in radians per minute.?

2PI radians = 360 degrees, or a full revolution. @ 33.33 revs/minute, the angular velocity of the disk is (2PI radians/revolution)*(33.33 revolutions/minute) = 209 radians/minute or 3.5 radians/sec.

The circumference of a circle is 2PI*R. If R = 14.5 cm, then the circumference is 91 cm. The angular velocity is 33.33 revs/minute and if each rev is 91 cm then the linear velocity is (91cm/rev)*(33.3 rev/min) = 3032 cm/minute. (3032 cm/minute) * (60 min/hour) * (1 inch / 2.54 cm) * (1 foot / inch) * (1 mile / 5280 feet) = 1.13 MPH

An LP record rotates at 33 1/3 rpm and is 12 inches in diameter. What is the angular velocity in rad/s for a?

An LP record rotates at 33 1/3 rpm and is 12 inches in diameter. What is the angular velocity in rad/s for a fly sitting on the outer edge of an LP rotating in a clockwise direction?

What is its angular velocity in rad/s if it spins at 1200 rpm?

diameter= 2.3m
radius = diameter/2 = 2.3/2 = 1.15m
if the propeller spins at 1200 rpm, its frequency, f is 1200/60 = 20 hertz
therefore, angular velocity, ω= 2πf = 2 X 22/7 X 20 = 880/7= 125.714286rad/s

linear velocity, v is given by
v=rω
v= 1.15 X 125.714286
v=144.571429 m/s

Centripetal acceleration, a is
a= ω²r
= (125.714286)²(1.15)
=18174.694 m/s²

If g is meant to be acceleration due to gravity and g= 9.81 m/s², then,
a = 18174.694/9.81
a=1852.67013 g m/s²

Math Help. Please help. Linear and Angular Velocity.?

i) Angular speed = 2pi*100/3 radians/min

ii) v = 5pi*27/2 inches/sec
v = (5pi*27/2)*3600/(5280*12) = 12 mph

iii) Angular speed = 48pi radians/min
Linear speed = 48pi * radius (not given)

What is the angular velocity in rad/s for a fly sitting on the outer edge of an LP rotating in a clockwise direction?

An LP record rotates at 33 1/3 rpm (revolutions per minute) and is 12.0 inches in diameter. What is the angular velocity in rad/s for a fly sitting on the outer edge of an LP rotating in a clockwise direction?

PHYSICS PROBLEM..An LP record rotates at 33 1/3 rpm ( revolutions per minutes)?

angular velocity in rad/s
ω = 33.5 / 60 * 2 π = 3.5081 rad /s
The angular speed expressed in radians is independent from the diameter

for a fly sitting on the outer edge of an LP ---- ω = 3.5081 rad /s
Tangential speed of the fly
velocity = 33.5 / 60 * π * 12 = 21.04 inch /s = 0.53442 m/s

Goodbye

If a record rotates at a constant speed of 33 1/3 rpm how many revolution does it make in 1sec?

1 minute = 60 seconds, and since 33 1/3 = 100/3 then
33 1/3 rpm = 100/3 rpm = (100/3)/60 rps = 100/180 rps = 0.5556 rps

For a record playing at 33 1/3 rpm, find the frequency and the angular velocity.?

f = (33 1/3)/ 60 = 0.5* sec^-1 where "*" denotes repeating digit

66 2/3π radians/min = 3.49 radians.sec^-1

Is 45 RPM a slow speed for vinyl records?

45rpm is a standard speed for Vinyl Single records, 16rpm is a slow speed for vinyl records but more about that later.RPM is revolutions per minute, the record rotates 45 times on the turntable every minute while the needle stays static, only moving slightly up and down.45rpm is the normal speed that 7” singles played, these would normally have 2 tracks, one on either side of the record.45rpm is also the normal speed that many but not all 12” Singles played (Sometimes called a Maxi Single). Some play at 33rpmSize of 12” Single compared to size of 7” Single - More space on the 12” for an extended version often a different mix of the single and wider grooves for increased bass sound if required.33rpm is the normal speed that 12” albums played, these normally would have 8 to 12 music tracks. A very small % are produced to play at 45rpm for Audio connoisseurs, typically the original album at 33rpm on one 12” disc would be released on 2 45rpm discs for better sound quality when played on specialist equipment. Only acts like the Beatles, Pink Floyd or Blue Note Jazz would ever receive this album reissue treatment or speed. Less than 1% of 12” albums produced play at 45rpm which is very rare and very specialist for albums.33rpm is the normal speed that 7”eps played (extra play), these would normally have 4 tracks.33rpm is also the normal speed that 10” albums played, with normally 8 tracks, these were in vogue from about 1949 to 1959 in parallel with the 12” Album which became the standard size.78rpm was the speed that much older records played. Early American shellac records were all 7-inch until 1901, when 10-inch records were introduced. 12-inch records joined them in 1903. By 1910, other sizes were retired and nearly all discs were either 10-inch or 12-inch, although both sizes were normally a bit smaller than their official diameter. Until Standardization in 1930, European 78 records played a fraction of a revolution slower than 78rpm and American 78s played a fraction of a revolution faster than 78 rpm.There are numerous other odd recording speeds for instance (a recent Jack White disc is played at 3rpm but this is novelty) the very odd audio record played at 16.66 rpm and a handful of old 1950s Jazz LPs, produced by the famous Prestige Jazz Label were produced at this speed. Normally these oddities would be relegated to the dustbin of time but as Miles Davis and John Coltrane featured expect to pay $500 upwards for any in mint condition.

A phonograph record on a turntable rotates at 33 1/3 rev/min. (a) What is the angular speed in rad/s?

w = (2π/60)*rpm = 3.49 rad/sec
