An analog clock typically has three ‘hands’, that track seconds, minutes, and hours, respectively. Find the angular velocity w of each hand in units of radians per second.
Homework Answers
Answer #1
Time period of full rotation of second hand = Ts = 60 sec
Time period of full rotation of minute hand = Tm = 60 minutes = 3600 sec
Time period of full rotation of hour hand = Th = 12 hours = 43200 sec
Angular velocity of second hand = 
s
Angular velocity of minute hand =
m
Angular velocity of hour hand =
h
= 2
/T
s
= 2/Ts
s
= 2/60
s
= 0.1047 rad/s
m
= 2/Tm
m
= 2/3600
m
= 1.745 x 10-3 rad/s
h
= 2/Th
h
= 2/43200
h
= 1.454 x 10-4 rad/s
Angular speed of second hand = 0.1047 rad/s
Angular speed of minute hand = 1.745 x 10-3 rad/s
Angular speed of hour hand = 1.454 x 10-4 rad/s
