Answer: Accelaration is 2.77 m/s*s
<h2 />
Explanation:
V0=0km/h=0m/s
V1=100 km/h=27.7 m/s
t=10s=
Use equation for accelaration : a=(V1-V0)/t
a=(0m/s-27.7m/s)/10s
a=-27.7s/10s
a=2.77m/s*s

Answer:
Distancia = 42.5 metros
Explanation:
Dados los siguientes datos;
Velocidad del sonido = 340 m/s
Tiempo = 8 segundos
Para encontrar la distancia desde la que se escuchó el sonido;
Distancia = velocidad/tiempo
Sustituyendo en la fórmula, tenemos;
Distancia = 340/8
Distancia = 42.5 metros
Answer:
Velocity v = 120 km/h
Time t = 30 s
Let Distance be d
First, we need to convert 120 km/h into m/s
1 km/h = (1000m)/(3600 s) = 5/18 m/s
So, 120 km/h = 120×5/18 m/s
So, v = 200/6 m/s
Now, velocity = distance/time
So d = v×t
So, d = (200/6) × 30
So, d = 1000 m
So, d = 1 km
Thus, distance travelled is 1 km
