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 speed of a sweep-second if the length is 2 cm and the hand is at 6'o clock mark?
It doesn't matter where it is on the clock. If the clock is working properly, the speed of the hand is constant.The hand's angular speed is 360 degrees per minute = 6 degrees per second.For the linear speed, the tip of the second-hand revolves in a circle whose circumference is(2 pi) times (length of the hand) = 4 pi centimeters.It revolves once per minute. So the speed of the tip is (4 pi) cm/minute, or (240 pi) cm/hour.In numbers, the speed at the tip is:12.6 cm/minute2.09 mm/sec7.54 meters/hour0.000469 mile/hour593.7 feet/day12.593 furlongs/fortnight.Notice that this is the speed at the second-hand's tip. Other points on it travel slower.The closer the point is to the center, the slower its speed is. At the center, it spins, butthe linear speed is zero.
What is the speed of a clock hand?
The speed of a clock hand depends on what the clock hand indicates the second hand is 2pi per 60seconds, the minute hand is 2pi per 3600 seconds and the hour hand is 2pi per 216000 seconds.
How do you convert radians per second to meters per minute?
First you must know the radius of whatever is moving in a circle. The relationship is: linear speed (meters/second) = angular speed (radians/second) x radius. The result, as hinted in the units, will be in meters/second. Converting that to meters/minute is easy; you just multiply by 60.
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.
