Explanation / Answer
The formula you will be using is 2*pi/seconds
a.) the second hand
2*pi/60 seconds
(becaus there are 60 seconds in a minute)
= .1047197551 rad/s
b.) the minute hand
2*pi/3600 seconds
(because i had to multiply 60*60 to see how many seconds were in 60 minutes)
=0.0017453293 rad/s
c.) the hour hand
2*pi/43200
(becaue there are 12 hours and there are 60 minutes in an hour so i converted to minutes which was 60*60=720; and then i had to multiply 720*60=43200 to give the seconds in 12 hours)
=1.45*10^ -4=0.000145
to find the angular acceleration
d.) the acceleration is constant on a clock that is working properly so the acceleration will be 0 because its not slowing down or speeding up its the same
