Draw a picture of what's happening and then after that it should become more clear on what equations you need to apply =).

SUMMARY
The discussion centers on solving an elastic collision problem involving a 25.0g object moving at 20.0cm/s colliding with a 10.0g object moving at 15.0cm/s. The final velocities after the collision are determined to be 17.1cm/s for the 25.0g object and 22.1cm/s for the 10.0g object. Key equations used include the conservation of momentum and conservation of kinetic energy, specifically mv1(initial) + mv2(initial) = mv1(final) + mv2(final) and 0.5mv1(initial)^2 + 0.5mv2(initial)^2 = 0.5mv1(final)^2 + 0.5mv2(final)^2. Participants emphasized the importance of correctly applying these equations to find the final velocities.
