Answer 1

Mike shoots a large marble (Marble A, mass: 0.05 kg) at a smaller marble (Marble B, mass: 0.03 kg) that is sitting still. Marble A was initially moving at a velocity of 0.6 m/s, but after the collision it has a velocity of –0.2 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.

Answer 2

You can usee conservation of momentum for the system:
initial momentum is equal to final momentum, and it's an elastic collision because the two marbles bounce off each other.

\[\textbf p_i = \textbf p_f \]
\[m_{Ai} \textbf v_{Ai} + m_{Bi} \textbf v_{Bi} = m_{Af} \textbf v_{Af} + m_{Bf} \textbf v_{Bf}\]

Can you specify see which variables go with which givens?

Answer 3

~~Can you see which variables go with each given?

Answer 4

each marble has it's own momentum, and momentum, p

\[ \textbf p = m \textbf v \]

where v is the velocity, and m is the mass
