Question

Si durante 15 segundos la velocidad de un móvil aumenta de 38.5 m/se a 95 m/se calcular la aceleración y el espacio recorrido

Answer 1

t = 15s
Vo = 38.5m/s
Vf = 95m/s
a =?
d =?

Vf = Vo + at
a = (Vf - Vo) /t
a = (95m/s-38.5m/s)/15s
a = 56.5m/s/15s
a = 3.77m/s²


d = (Vo +Vf)t/2
d = (38.5m/s+95m/s)×15s/2
d = 133.5m/s×15s/2
d = 1001.25m
