Group Title
Ina shoots a large marble (Marble A, mass: 0.08 kg) at a smaller marble (Marble B, mass: 0.05 kg) that is sitting still. Marble A was initially moving at a velocity of 0.5 m/s, but after the collision it has a velocity of –0.1 m/s. What is the resulting velocity of marble B after the collision? Be sure to show your work for solving this problem along with the final answer.

initial linear momentum=final linear momentum so 0.08*0.5=0.1*0.08+0.05*v v=0.96

Now, what we have is : the condition I mentioned above in the form of a diagram is of before collision... Now here is the condition of the marbles AFTER collision in the form of a diagram... dw:1351258449229:dw

now using the law of conservation of momentum : Momentum before collision = Momentum after collision @AshleyBcdd are you getting what I am telling here?

\[\large{m_A u_A + m_B u_B = m_A v_A + m_B v_B }\] \[\large{0.08 kg\times (0.05 ms^{1}) + 0.05 kg \times 0 ms^{1} = 0.08 kg \times 0.01 ms^{1} \\+ 0.05 kg \times v_B }\]

you will get : 0.096 after solving for v_B
