Answer:
1 hour
Explanation:
Since the definition of velocity is , we can calculate the position at time t of an object moving at speed v with
.
The position of the first ferry is
The position of the second ferry is
We want to know when they will be 6 miles apart. This means, if we call that distance d, that we want to know when the difference between their positions will be d, or (we know that at the beginning the position of the ferry 1 is of higher value than that of ferry 2 since it left before).
We use our previous formulas then:
Since we want the time, we do:
And substitute our values:
Answer:
Velocidad final, V = 40 m/s
Explanation:
Dados los siguientes datos;
Aceleración = 5 m/s²
Velocidad inicial = 0 m/s (ya que comienza desde el reposo)
Tiempo = 8 segundos
Para encontrar la velocidad final, usaríamos la primera ecuación de movimiento;
Dónde;
- V es la velocidad final.
- U es la velocidad inicial.
- a es la aceleración.
- t es el tiempo medido en segundos.
Sustituyendo en la fórmula, tenemos;
<em>Velocidad final, V = 40 m/s</em>
