Question

Angular speed of hour hand of a clock in degree per second ?

Answer 1

The answer is `(0.00833^@)/s`

Explanation:

The hour hand goes `360^@` in 12 hours. So we can say that its angular speed is
`(360^@)/(12 "hours") = (30^@)/(1 "hours")`

Now I just need to convert units.

`(30^@)/cancel(1 "hour") * cancel(1 "hour")/(3600 s) = (0.00833^@)/s`

I hope this helps,
