A car moving 14.4 m/s has 18,100 kg•m/s of momentum. What is its mass?

1256.944kg

And this is how since we want mass (kg)

we multiply 18100kgm/s with 1/14.4 m/s

the above equation will cancel out m/s and leave us with 18100/14.4 kg

this gives 1256.944kg

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
