The angular velocity of a wheel taking 45 seconds to rotate once is 2 2/3 pi radians per minute. The diameter of the wheel does not matter in this case.

What is the angular speed of the minute hand in radian per second?
Angular speed = 2*pi radians per 60 seconds = pi/30 radians per second.
An electric fan is turned off and its angular velocity decreases uniformly from 550 rev per min to 200 in rev per min time interval of length 4.50 sec?
(550 - 200) rev per minute = -350 rev per minute / 60 sec per minute = (-35/6 rev per second) change in angular velocityAngular acceleration = (change in angular velocity) / (time for the change) =(-35/6 rev per second) x (2 pi radians per rev) / 4.5 seconds = -8.1449 radians per second2
Convert rpm to rad per sec?
1 revolution = 2π radians 1 minute = 60 seconds → 1 rpm = 1 revolution / 1 minute = 2π radians / 60 seconds = π/30 radians/seconds = π/30 rad per sec → to convert rpm to rad per sec multiply by π (pi) and divide by 30.
What is her velocity if it takes her 60 seconds?
Takes her 60 seconds to do what? Travel 1 mile? Travel 10 miles?
What is the velocity of an object that travels 15 meters in 2 seconds?
7.5
What is the angular velocity of the wheel before braking began if the wheel rotates through 6 radians in 2 seconds as it is uniformly brought to rest?
It was 6 radians per second. Angular acceleration = -3 radians per second2 Initial angular velocity = 6 radians per second. Final angular velocity = zero. Average angular velocity = 3 radians per second. Angular displacement in 2 seconds = 3 x 2 = 6 radians.
If a wheel turns at 180 RPM what is it's angular velocity in radians per seconds?
180 rpm = 180/60 = 3 rps Each revolution equates to an angular movement of 2π radians. Therefore angular velocity = 3 x 2π = 6π = 18.85 radians per second (2dp)
How the angular velocity of binary stars are calculated?
By observation. The angular velocity can be derived from the period. If, for example, it takes a day (86,400 seconds) for a full revolution, then the angular velocity will be (2 x pi / 86400) radians per second.
Define angular velocityWhat is its SI unit?
Angular velocity is a measurement of how fast something is turning. Everyone has heard of "RPM", which stands for "Revolutions Per Minute" ... how many complete turns an object makes in one minute. That's a perfectly good measurement of angular velocity, although in Physics, angular velocity is normally given in different units. The standard unit for angular velocity is "radians per second". Each complete turn covers (2 pi) radians (same as 360 degrees). And there are 60 seconds in one minute. So if you know the RPM, you can multiply RPM by (2 pi / 60) = 0.10472 to get angular velocity in standard units. An old LP phonograph record (remember those ?) playing at 33-1/3 RPM has an angular velocity of about 3.5 radians per second. A car engine idling at 1,000 RPM is turning at about 104.7 radians per second.
How do you convert radians per seconds into degrees?
You cannot. Radians per second is a measure of angular speed whereas degrees are an angular measure.
What is the angular speed of the minute hand in radian per second?
Angular speed = 2*pi radians per 60 seconds = pi/30 radians per second.
What is the formula to convert angular speed to linear speed?
The linear (tangential) speed of a point on a spinning circle is(angular speed of the spin) x (radius of the circle). Note that this only works if the angular speed is in units of radians/time .To convert degrees to radians, multiply by (pi)/180 ... about 0.01745 .
Define angular speed?
In physics, angular frequency ω (also referred to by the terms angular speed, radial frequency, circular frequency, orbital frequency, radian frequency, and pulsatance) is a scalar measure of rotation rate. Angular frequency (or angular speed) is the magnitude of the vector quantity angular velocity. The term angular frequency vector is sometimes used as a synonym for the vector quantity angular velocity.[1]One revolution is equal to 2π radians, hence[1][2]whereω is the angular frequency or angular speed (measured in radians per second), T is the period (measured in seconds), f is the ordinary frequency (measured in hertz) (sometimes symbolised with ν),
A bicycle wheel rotates uniformly through 2 revolutions in 4 seconds What is the average angular speed of the wheel?
Angular velocity (omega) = delta theta / delta time omega = 2 /4 = .5 rev/s = pi radians/s
How do you find the angular velocity of second hand of a watch?
Angular velocity has units of (angle per time), usually stated in radians per second. (1 whole revolution = 2 pi radians) Assuming the watch is operating properly, the second hand turns once per minute. 1 rev/minute = (2 pi) / (60 seconds) = pi/30radians per second. This is usually good enough for most physicists, but if they demand a number, it's easy to work it out: pi = 3.14159 (rounded) Angular velocity = pi/30 = 0.10472 radians per second. Or if you really want the physicist to take notice, tell him "104.72 milliradians per second".
A is the unit used to measure angles?
degrees, minutes and seconds. (and radians are also a standard unit of angular measure).
What is the dimension of angle theta?
It is angular displacement which may be measured in radians, or degrees-minutes-seconds. In 3-D it would be stradians
