If you wanna run away with me, I know a galaxy

And I can take you for a ride (for a ride)

I had a premonition that we fell into a rhythm

Where the music don't stop for life (for life)

Glitter in the sky, glitter in my eyes

Shining just the way I like (I like)

If you're feeling like you need a little bit of company

You met me at the perfect time

You want me, I want you, baby

My sugarboo, I'm levitating

The Milky Way is liberating

Yeah, yeah, yeah              

I got you, moonlight, you're my starlight

I need you all night, come on, dance with me

I got you, moonlight, you're my starlight (you're the moonlight)

I need you all night, come on, dance with me (come and dance with me)

6/12=1/2

step-by-step explanation:

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
