Which of the following has the most momentum?

an ant moving at 1 m/s

a bird flying at 4 m/s

a cat moving at 13 m/s

you riding your bike at 12 m/s

you riding your bike at 12m/s

Explanation: this is because momentum P = mass x velocity. With a bigger mass and a velocity of about 12m/s, you really have a great momentum.

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
