∙ 13y agoWow-here goes. 2 pi radians=360 degrees=60 sec.
so we have (2 pi rad)/60 sec=(6.28 rad)/60 sec and is ~ .21 rad/sec
eh?

∙ 13y ago1 radian = approx 9.5 minutes so 2.5 radians = 23.9 minutes. Therefore 2.5 p radians = 23.9p minutes.

the second hand
The angular speed (expressed, for example, in radians/second, degrees/minute, etc.) doesn't depend on the length of the hand. To calculate this, just divide a full circumference (= 360 degrees, or 2 x pi if you use radians) by the time it takes to turn around once. To calculate the linear speed, multiply the radius by 2 x pi, to get the circumference. Then divide that by the time it takes to turn around once. For example, for the minute hand you would divide by 1 hour.
The second hand on the clock circles 420 times in 7 hours.
The angular velocity of the second hand of a clock is pi/30 radians per second.
The magnitude of the angular velocity of the second hand of a clock is 6 degrees per second (360 degrees divided by 60 seconds), while the angular acceleration is zero since the second hand moves at a constant speed.
The second hand of a clock completes a full revolution every 60 seconds, which is equal to 2π radians. Therefore, in 30 seconds, the second hand turns through π radians.
No the 'second hand' of a clock has a higher velocity, it makes one rotation each minute, while the minute hand makes on rotation each hour and the hour hand makes one rotation every 12 hours.
A clock's second hand makes one complete revolution each minute. Thus, by definition, it is rotating at one revolution per minute or one RPM. That's its "rotational velocity" and it is the same no matter how big or small the clock might be. The actual velocity that the tip of the second hand might trace out as it revolves around the center of the clock will vary with the length of the second hand. The longer the hand, the faster the tip moves around the circumference.
Since there are 2 Pi radians in one complete turn, then the minute hand turns 1.75 * 2 Pi radians in 1.75 hours.
1 radian = approx 9.5 minutes so 2.5 radians = 23.9 minutes. Therefore 2.5 p radians = 23.9p minutes.

It is pi/3 radians (60 degrees).
If the velocity of the moving clock is comparable to the speed of light, it will experience time dilation, length contraction, and relativistic effects according to the theory of special relativity. The path of the clock will be distorted from the perspective of a stationary observer, and its time measurements will differ significantly from those made by a stationary clock.
