Question

I train has a mass of 710000 kg and a top speed of 71 m s what is the momentum of the train

If a second train has a momentum of 56 million kgms which has one has the greater momentum

Answer 1

The momentum of the first train is 50410000 kg·m/s, and the second train has a momentum of 56000000 kg·m/s. Therefore, the second train has the greater momentum.

Step-by-step explanation:

To determine which train has the greater momentum, we first need to calculate the momentum of the first train. The momentum of an object is given by the product of its mass and velocity. Thus, the momentum (p) of the first train is:

p = mass × velocity

p = 710000 kg × 71 m/s

p = 50410000 kg·m/s

The second train has a given momentum of 56000000 kg·m/s. Comparing the two:

• First train momentum: 50410000 kg·m/s
• Second train momentum: 56000000 kg·m/s

Since 56000000 kg·m/s is larger than 50410000 kg·m/s, the second train has the greater momentum.
