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:

-0.10472[tex]\frac{rad}{s}[/tex]

Explanation:

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

The formula for period is:

[tex]T = \dfrac{2\pi}{\omega}[/tex]

Solve for [tex]\omega\\[/tex] and you get:

[tex]\omega=\dfrac{2\pi}{T}[/tex]

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