Rotary motion

Find the orbital time, rotational frequency, and angular rate of the second and minute hands on the watch.

Correct answer:

T1 =  60 s
f1 =  0.0167 Hz
ω1 =  0.1047 1/rad
T2 =  3600 s
f2 =  0.0003 Hz
ω2 =  0.0017 1/rad

Step-by-step explanation:

T1=60=60 s
f1=1/T1=1/60=0.0167 Hz
ω1=2π f1=2 3.1416 0.0167=0.1047 1/rad
T2=60 60=3600 s
f2=1/T2=1/3600=0.0003 Hz
ω2=2π f2=2 3.1416 0.0003=0.0017 1/rad
