Question

Any Acellus folk figure out the answer to this one??? I CANNOT for the life of me.

What is the angular velocity of the minute hand of a clock?
[?] rad/s

Hint: It travels clockwise and takes 60 minutes to make one revolution.



(not 1.25, 1.7, 1800, 30, 60, 0.1047)

Answer 1

-0.10472
`(rad)/(s)`

Step-by-step explanation:

Remember that any clockwise rotation is considered negative, and any counterclockwise rotation is considered positive.

The formula for period is:

`T = (2\pi)/(\omega)`

Solve for
`\omega\\` and you get:

`\omega=(2\pi)/(T)`

The period is 60 seconds so make that division and you're left with -0.10472
`(rad)/(s)` or -0.10
`(rad)/(s)` if significant figures apply (negative because the rotation is clockwise).
