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 angular velocity in radians per minute of ferris wheel 250 feet in diameter that takes 45 seconds to rotate once?
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.
A remote control car's wheel accelerates at 22.4 rad-sec squared If the wheel begins with an angular speed of 10.8 rad-sec what is the wheel's angular speed after exactly 3 turns?
A measure of how fast a rotating body is changing its angular position. The average angular speed (w) is obtained by dividing the http://www.answers.com/topic/angular-distance-2 through which the body rotates by the time taken: w = θ/t, where θ = angular distance, and t = time taken in seconds.
How many revolutions in seconds does light travel 1 mile?
None. It's a trick question. Light travels in firsts.
What 3 variables that might affect the number of cycles the pendulum makes in 15 seconds?
The length of the pendulum, the angular displacement of the pendulum and the force of gravity. The displacement can have a significant effect if it is not through a small angle.
What is the angular velocity of a 6-foot pendulum that takes 3 seconds to complete an arc of 14.13 feet use 3.14 for pi?

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
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.
What is the small-angle formula?
The small angle formula is used for measuring the distance to a far away object when the actual size and angular size are known, or for finding out the actual size of a faraway object when the distance to the object and angular size are known. In arc-seconds: a = 206265 x D/d where a = the angular size of the object in arc-seconds D = the actual linear size of an object in km d = the distance to the object in km 206265 = the number of arc-seconds in a complete circle divided by 2pi In Radians: a = D/d where a = angular size of object in radians
If a motor turns at 0.6 RPM how many revolutions is that in sixty seconds?
There are 60 seconds in a Minute. RPM is revolutions per Minute. So your question answers itself.
What is 99 minutes and 59 seconds?
A time or an angular measurement.
What quantity minute?
60 seconds, if measuring time or angular separation.
What is the unit of measurement used for reading lines of longitude and latitude?
You would use angular degrees or angular degrees plus minutes and seconds.
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 rpm?
rpm is REVOLUTIONS PER MINUTEthis is how many times something revolves a complete cycle in one minuteAnswerRPM stands for REVOLUTIONS PER MINUTE. This is a measure of how many times your tires revolve in a single minute. Answerrpm means revolutions per minute Answerrpm measures the exact number of times the tire rotates in a single 60 seconds
How long will it take a pulley rotating at 8 radians per second to make 50 complete revolutions?
(1 sec/8 rad) * (2 pi rad/1 rev) * 50 rev = 12.5 * pi seconds about 39.27 seconds
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.
