What is the magnitude of velocity for a 2,000 kg car possessing 3,000 kg(*)m/s of momentum?
1 answer:
The magnitude of velocity for this car is equal to 1.5 m/s.
<u>Given the following data:</u>
- Momentum of car = 3,000 kgm/s.
- Mass of car = 2,000 kg.
To calculate the magnitude of velocity for this car:
<h3>What is momentum?</h3>In Science, momentum simply means a multiplication of the mass of an object and its velocity.
Mathematically, momentum is giving by the formula;
Making velocity the subject of formula, we have:
Substituting the given parameters into the formula, we have;
Velocity = 1.5 m/s.

Answer:
El avión recorrió 45 km en los 180 s.
Explanation:
La relación entre velocidad, distancia y tiempo se da de la siguiente manera;
Por lo cual los parámetros dados son los siguientes;
Velocidad = 900 km/h = 250 m / s
Tiempo = 180 s
Estamos obligados a calcular la distancia recorrida
De la ecuación para la velocidad dada arriba, tenemos;
Distancia recorrida = Velocidad pf viaje × Tiempo de viaje
Distancia recorrida = 900 km/h × 180 s = 900
Distancia recorrida = 900 km/h × 1 h/60 min × 1 min/60 s × 180 s = 45 km
Por lo tanto, el avión viajó 45 km en 180 s.
