What is the rotational speed of a wall clock that has a sweeping hand that is Cm long?

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.

What is the Little hand on the clock?
The little hand on the clock is known as the hour hand.
Which has more momentum a second hand on a clock or a minute hand on a clock?
the second hand
Which hand on a clock is the minute hand?
It is the long hand.
What is the minute hand on the clock?
The long hand
What is the rotational speed of the second hand on a clock that measures the seconds?
It takes 1 minute to rotate 1 time.
What is the difference between oscillating and rotational motion?
Rotational motion is motion which emulates that of the minute hand of a clock. Oscillating motion is motion which emulates that of the pendulum.
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.
What is the speed of a clock's second hand?
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.
How do you write a calculation for the speed of a minute hand on a clock?
its formula is 2pi r
What is the speed of a clock's minute hand?
it moves at one click every 60 seconds

If the length of the minute hand of a clock is 5cm how can you calculate its speed?
The minute hand traces its path around the clock once in an hour. The distance travelled by the tip of the hand in this time is 2 x pi x 5cm.The speed is then 10pi cm/hour, which is 8.73 x 10-5 ms-1.
Which hand is the hour hand on a clock?
The short hand is the hour hand on a clock.
What is the Little hand on the clock?
The little hand on the clock is known as the hour hand.
What is the angular acceleration of the minute hand of a clock?
The hands of a clock move at a constant speed, not slowing or speeding up. Therefore, the acceleration is a constant 0 rad/s2
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.
