Cassy shoots a large marble (Marble A, mass: 0.06kg) at a smaller marble (Marble B, mass: 0.03kg) that is sitting still. Marble

A was initially moving at a velocity of 0.7m/s, but after the collision it has a velocity of -.02m/s. What is the resulting velocity of marble B after the collision? Be sure to show your work.

The question can be solved using conservation of linear momentum.

M_{a} = 0.06kg and M_{b} = 0.03kg

Let the initial velocity of Marble A be , V_{a1} = 0.7m/s

Let the initial velocity of Marble B be, V_{b1} = 0m/s

Let the velocity of Marble A after collisiong , V_{a2}= -0,02m/s

Let the velocity of Marble B after collision be V_{b2}

From the conservation of linear momentum equation. We get,

M_{a}V_{a1}+M_{b}V_{b1}=M_{a}V_{a2}+M_{b}V_{b2}

Substituting the values we get,

(0.06)(0.7) + 0 = (0.06)(-0.02) + (0.03)V_{b2}

we get, V_{b2} = 1.44m/s

"In a pure substance all the particles must be identical; therefore pure substances are composed only of elements." Do you agree
kenny6666 [7]

I do not agree with the statement.
The "substance" can be a compound.  It's "pure"
as long as there's nothing else in it but its name.

'Pure' water is 100% H₂O with nothing else in it.
'Pure' table salt is 100% NaCl with nothing else in it.
'Pure' carbon dioxide is 100% CO₂ with nothing else in it.

These example substances are all compounds, not elements.

Gas
Brut [27]
A: what is it called when a solid jumps straight to a gas?
B: what is it called when a liquid becomes a gas?
C: what is it called when a solid changes into a liquid?

Im sure you can at least figure out the last one! (hint: this happens when ice becomes water)

Manipulate p+x=r to solve for x
Tanzania [10]
X=r-p. Maybe I don't understand, but I am assuming that you need to isolate for X? you simply subtract p from both sides.<span />
