| Well, it's
time to calculate the rotational velocity of the second hand of this watch!
Remember now...not the hour hand, not the minute hand, but the second hand (even though it's not used very much!). This is a normal clock, so the hands move just like the old clock on the wall. My, how physics time phlys! |
The second hand takes 60 seconds
to make one rotation. One rotation is equal to 2(pi) radians. So,
vrot = 2(3.14 rad) / 60 s = 0.105 rad/s |
