Step-by-step explanation:
The end of the arrow of the hand rotates in a circle of radius 5 cm. It moves the circumference = 2 π 5 cm in one rotation, that is 60 minutes = 3600 seconds.
So the LINEAR speed of the TIP of the minute hand = 2π * 0.05 meter / 3600 sec
= 0.0000872 meters/sec or 0.08 mm/sec
= 31.4 cm / hour
The angular speed of the minutes hand is :
360 degrees / 3600 seconds = 0.1 degree/second
