Los datos que tienes son:
vi = 0 m/s
vf = 80 km/h
t = 10 s
a = ?
d = ?
Pasas las unidades al SI
vf = (80 km/h) (1000 m) / (1 km) (1 h) / (3600 s) = 22,22 m/s
Calculamos la aceleración
a = (vf - vi)/t
a = (22,22 m/s - 0 m/s)/10s
a = (22,22 m/s)/10s
a = 2,22 m/s²------------------Respuesta
Calculamos la distancia
d = (vf + vi)/2 * t
d = (22,22 m/s + 0 m/s)/2 * 10s
d = (22,22 m/s)/2 * 10s
d = 11,11 m * 10
d = 111,1 m-----------Respuesta
