Calculate the average angular velocity of the hour hand of the of a clock.

Text Solution

Verified by Experts

The hour completes one round in 12 hours. One round make an angular displacement ` 2pi`
` omega = (Deltatheta)/(Deltat)`
`= ( 2 pi rad)/( 12 hr) `
` ( 2pi)/(12xx 3600) "rad"//s^(-1)`
`pi/21600 " rad" s^(-1)`
