Answer 1

Answer:

2. inertia of a train is more because it has more mass

1. momentum = mass × velocity

Answer 2

Answer:

1. Mass and velocity are both directly proportional to the momentum. If you increase either mass or velocity, the momentum of the object increases proportionally. If you double the mass or velocity you double the momentum

2. we know that inertia is directly proportional to mass. Therefore, between train and bicycle train has much more mass therefore the inertia of the train is much more than that of a bicycle
