a clock has a minute hand with length 15 cm,let p point at the tip of the minute hand.
find the angular velocity of p in rad/hr?
find the linear velocity in cm/min?
**
In one hour the minute hand makes one revolution=2π radians
angular velocity, p=2π radians/hour
..
In 60 minutes the minute hand makes one revolution.
In one revolution the tip of the minute hand travels 2πr=2π15=30π cm
linear velocity=30π/60=π/2 cm/min
