What does slam into mean?

What does "slam into" mean?

The prompt about impulse and momentum says "a large comet or asteroid slammed into the earth". Does the prompt means that the comet or asteroid combined with the Earth after collision and moved together at same speed after the collision?

What's a 'prompt' in this context?

I asked prof and he said I should make an assumption about the motion after collision. Thank you DaveC426913.

I think the phrase "slammed into" could equally well be followed by any number of phrases such as, for example, (1) "and was absorbed by", (2) "and bounced off off"

@phinds
Yes exactly! So I was asked to make assumptions.
