Suppose two spheres approach each other at 1 m/s from opposite directions. Their total momentum is zero. After the collision, they both zoom off at 1m/s in opposite directions.
What is their momentum? What do you know about the mass of the two spheres?

Their momentum is zero and I know nothing about the mass!
Well, we can't figure it out because the mass is not given. To find momentum, you need mass and velocity.
Ben is right
Both spheres momentum is probably about 1m/s. Both spheres have the same mass because if they didn't then the sphere with the greater mass would push the object with less mass in it's own direction.
What Ben said
But we can't know sure what the momentum is because the example only gives speed not velocity.
What the heck idk I don't understand this can you teach us please Mr. Ruby?
momentum is zero
the momentum is because the example only gives speed not velocity.
I don't know.
We cant figure it out without mass.
We can't figure it out.
I don't know.
As Ben had said you can't figure it out cause the mass is not given. You need mass and velocity to find momentum.
wiithout mass
We need the mass to solve it.

THERES NO MASS MR RUBY
You copied ben please post your own.
NO MASS
The momentum stays at zero. Due to the law of conversion of momentum says that the total momentum when two object collide stays the same.
Sorry, their momentum is zero because the law of conservation of momentum says that the total momentum of objects that collide with each other the momentum does not change. So it would be zero as the blog had said. And the mass of the two spheres are the same.
OWEN: Zero
No mass?

AW MEH GAWD SPHERE CILLISIN IT GUUTA BEH NER MASE
(oh my god sphere collision it's gotta be no mass)
There is no mass so we can't find the momentum.
no mass
Since everyone else is saying this, we need the mass or something I'm not really sure.
There is no mass so we can's find the momentum.
Theres no mass in the equation.
No mass and no momentum
There is no mass
Yeah Ben please post your own.
YOU COPIED SOMEONE AND PUT IT INTO YOUR OWN WORDS!!!!!!!!!!!!!
no mass
qwertyuiop
you can not tell the mass
loganm
No mass and no momentum
No mass and no momentum
Mass is equal between the two spheres.
The mass is the same, and the momentum is 0.
The mass is the same and no momentum.
The mass would be the same with no momentum.
Zero
The mass is the same without momentum
The mass would be the same without any amount of momentum.
The spheres have the same mass, and the momentum is zero
Their mass is the same because they both hit each other and go the same distance and same speed
The mass is the same, and the momentum is 0.
It's 0.
0
its 0
is nothingness a kind of matter
