The 2.00-cm-long second hand on a watch rotates smoothly. what is its angular velocity?

Question

Question

Answer 1

Answer #1

Angular velocity w = angle(radians)/time(sec)
For a second hand, the angle is 2π radians and the time is 60 sec;
w = 2π/60 =0.1047 rad/sec

Answer 2

Answer #2

2 * pi * 3cm = .314cm/s
