Calculate the angular velocity and the linear velocity of the tip of the second hand of a clock, if the second hand is 4cm long.

Open in App
Solution

Given: length of minute hand 4cm which is also radius of circular path of second hand.
To find the angular velocity and the linear velocity of the tip of the second hand of a clock,
Solution:
As per the given criteria,
r=4cm
We know that angular velocity,
ω=angletimeω=2π60secω=π30rad/s
And Linear velocity,
v=rωv=4×π30v=0.42cm/sec
