Question

What is the angular velocity of the minute hand of a clock? If the minute hand is 5 cm long, what is the linear velocity of its tip? 

Answer 1

Given: R = 5 cm = 5 × 10⁻² m, 

T = 1h = 3600 s 

For the minute hand of the clock, 

 i. The angular velocity is 1.74 × 10^–3 rad/s. 

 ii. The linear velocity of the tip is 8.7 × 10^–5 m/s.
