Question
Which of the following has the greatest momentum?Select an answerAA car moving at 10 m/s with a mass of 1000 kgBA truck moving at 5 m/s with a mass of 5000 kgCA motorcycle moving at 20 m/s with a mass of 200 kgDA bicycle moving at 30 m/s with a mass of 50 kg
Solution
Para determinar cuál de los objetos tiene el mayor momento, utilizamos la fórmula del momento lineal (p):
donde es la masa y es la velocidad.
A. Un coche que se mueve a 10 m/s con una masa de 1000 kg:
B. Un camión que se mueve a 5 m/s con una masa de 5000 kg:
C. Una motocicleta que se mueve a 20 m/s con una masa de 200 kg:
D. Una bicicleta que se mueve a 30 m/s con una masa de 50 kg:
Comparando los momentos calculados:
El camión que se mueve a 5 m/s con una masa de 5000 kg tiene el mayor momento, con . Por lo tanto, la respuesta correcta es:
B. Un camión que se mueve a 5 m/s con una masa de 5000 kg.
