Maths Puzzle
What is the ratio of angular velocity of the second hand to the minute hand to the hour hand in a wall clock ?
Read Solution (Total 1)
-
- The second hand turns at the rate of 2Pi radians per minute which is 2Pi/60 radians per second or Pi/30 radians per second.
Linear velocity is:
v = rw
where r is the radius and w is the angular velocity in radians per second
r = 10 inches or 0.254 meters
w = Pi/30
So v = 0.254 x Pi /30 = 0.027 meters per second - 11 years agoHelpfull: Yes(2) No(2)
