Homework Equations




The Attempt at a Solution



for minute hand:
ωmin = rad in one rev / time = 2π/(60s) = 0.105 rad/s
for hour hand:
ωhr = 2π/(3600s) = 0.00174 rad/s

So .105, .00174 should be the answer...?

It's telling me these are wrong... can't figure out what I'm doing wrong.

Thanks in advance
