Vf= 50 km/h = 13,89 m/s
t= 0.3 m= 18 s
a= Vf-V0/t= 13.89 m/s- 0= 13.89 m/s / 18 s=
a= 8.77 m/s2
vi = 0 m/s
t = 0,3 minutos
vf = 50 km/h
a = ?
Pasas las unidades al SI
1 minuto = 60 segundos
60 * 0,3 = 18 segundos
50 km/h / 3,6 = 13,89 m/s
Calculamos la aceleración.
a = (vf - vi)/t
a = (13,89 m/s - 0 m/s)/18s
a = (13,89 m/s)/18s
a = 0,77 m/s²
La aceleración es 0,77 m/s²
