# Which has more momentum, an object with a mass of #3kg# moving at #14m/s# or an object with a mass of #12kg# moving at #6m/s#?

The object with the mass of 12kg has more momentum.

Therefore, the object of m= 12kg has more momentum.

To calculate momentum, you multiply mass by velocity.

For the first object: momentum = mass x velocity = 3 kg x 14 m/s = 42 kg*m/s.
For the second object: momentum = mass x velocity = 12 kg x 6 m/s = 72 kg*m/s.

Therefore, the object with a mass of 12 kg moving at 6 m/s has more momentum, with 72 kg*m/s, compared to the object with a mass of 3 kg moving at 14 m/s, with 42 kg*m/s.

- A ball with a mass of #7 kg# moving at #4 m/s# hits a still ball with a mass of #21 kg#. If the first ball stops moving, how fast is the second ball moving? How much kinetic energy was lost as heat in the collision?
- A ball with a mass of #3 kg# moving at #15 m/s# hits a still ball with a mass of #17 kg#. If the first ball stops moving, how fast is the second ball moving? How much kinetic energy was lost as heat in the collision?
