Answer:
Distancia = 50.04 metros
Explanation:
Dados los siguientes datos;
Velocidad = 10 km/h
Tiempo = 18 segundos
Para encontrar la distancia;
Conversión:
10 km/h = 10 * 1000/3600 = 2.78 m/s
Distancia = velocidad * tiempo
Distancia = 2.78 * 18
Distancia = 50.04 metros
Por lo tanto, el tren viajaría 50.04 metros antes de detenerse por completo.
Answer:
True.
Explanation:
Hypotheses are supposed to be tested, to be proven correct. They usually start from a small thought without 100% correct, but as you do further testing, they become stronger.
Acceleration = change in velocity/time
By F = ma,
6 = 33 x change in velocity / 9
change in velocity = +1.636 m/s
