Donde:
w = 2π / T (Periodo).
r = radio.
Datos:
Tenemos la frecuencia: 5 rev. por segundo.(Hertz)
Para hallar el periodo:
T = 1 /F
T = 1 / 5
T = 0.2 s
Entonces: w = (2π / 0.2 s)
r = 3 m
Reemplazamos:
V = (2π / 0.2 s) * 3 m
V = 10π s⁻¹ * 3 m
*Nota:10π = 31.4 s⁻¹ (3cs)
V = 31. 4 s⁻¹ * 3 m
V = 94.2 ms⁻¹
