Ok so let's start off with this

KE=(1/2)(M)(Speed$$^{2}$$)

Astro · Answer

Woah that is supposed to be Speed to the second (Speed^2)

lmao

So let's jump to the first object. Would you like it better if I walk you through it first then write it, or show you it then explain it?

which ever works for you

Sounds good!

Astro · Answer

So we are going to follow the formula above to complete this. Which should be EZ

(1/2)(Mass=2KG)(Speed^2= 2m/s)^2

Astro · Answer

So that is basically saying 1/2 times the mass(2KG) times the speed to the second(2m/s)^2

Joe348 · Answer

thats 4 and the other is 18

Astro · Answer

Wait...The first one

Joe348 · Answer

yeah the two objects

I'm talking about the first one at the moment the mass=2 and it's traveling at 2m/s

Joe348 · Answer

yes?

Astro · Answer

So what are you trying to say? I do not understand

Joe348 · Answer

wait what are you trying to say lol?

Joe348 · Answer

(I dont have much longer to be on here btw)

Astro · Answer

OHH, sorry I didn't understand what you were saying. You are correct. The first one is 4 and the second one is 18 but. It is going 10 meters right?
