vi = 50 km/h
vf = 70 km/h
t = 25 s
a = ?
d = ?
Pasas las unidades al SI
vi = (50 km/h) (1000 m) / (1 km) (1 h) / (3600 s) = 13,89 m/s
vf = (70 km/h) (1000 m) / (1 km) (1 h) / (3600 s) = 19,44 m/s
Calculamos aceleración.
a = (vf - vi)/t
a = (19,44 m/s - 13,89 m/s)/25s
a = (5,55 m/s)/25s
a = 0,220 m/s²
Calculamos distancia.
d = (vf + vi)/2 * t
d = (19,44 m/s + 13,89 m/s)/2 * 12s
d = (33,33 m/s)/2 * 12s
d = 16,67 m/s * 12s
d = 200,04 m
