and brainliest cuz I also answered the question
Explanation:
I have an older brother
free points that you don't have to answer correctly
Answer:
La profesora lo habla durante la clase.
C) Esta, should be correct
3240km/h^2 o 1/4m/s^2
0, 5km o 500m
Usando km/h
a=(90-72)/(1/180)=3240km/h^2
(1/3)min=(1/3)*(1/60)=1/180s
Usando m/min
72km/h*(1000m/1km)*(1h/3600s)= 20m/min
90km/h*(1000m/1km)*(1h/3600)= 25m/min
1/3min*(60s/1min)= 20s
a=(25-20)/20=1/4m/s^2
Fórmula del espacio recorrido
Pf=Pi+Vit+at^2
P=0+72*(1/180)+3240*(1/180)^2
P=0,5km
P=0+20*(20)+(1/4)*(20)^2
P=500m
