Find the linear speed of tip of minute hand of the clock , if its length is 0.25m ?
Length = 0.25 m will be equal to radius
Radius (R) = 0.25 m
Minute clock complete a circle in 60 mins
60 mins = 60 * 60 = 3600 sec
1 complete circle = 2 π R
= 2 * 3.14 * 0.25
= 1.57 m
Linear Speed = 1.57/3600 m/s
= 0.00043611 m/s
= 436.11 * 10⁻⁶ m/s
= 436.11 μm/s
Anglular Speed = 2π / 3600
= 2 * 3.14/3600
= 0.001744 rad/s
= 1.744 * 10⁻³ rad/s
