vi = 70 m/s
Vf = 100 m/s
t = 15 s
a = ?
d = ?
Calculamos la aceleración :
a = (vf - vi)/t
a = (100 m/s - 70 m/s)/15 s
a = 30 m/s / 15 s
a = 2 m/s²
La aceleración es 2 m/s²
Calculamos la distancia o espacio :
d = (vi + vf)/2 * t
d = (70 m/s + 100 m/s)/2 * 15 s
d = (170 m/s)/2 * 15s
d = 85 m/s * 15 s
d = 1275 m
El espacio es de 1275 metros
