Velocidad angular = (angulo total) / (tiempo total)
Velocidad angular = (1080 grados) / (20 segundos)
Velocidad angular = (1080/20) g/s
Velocidad angular = 54 g/s
Pero 180 grados = π radianes
V.A. = (54 g/s) x (π rad / 180 g)
V.A. = (54π gr-rad / 180 seg-gr)
<em>V.A. = 0.3π rad/seg</em>
V.A. = aproximadamente 0.942 rad/seg
