How do your measured and predicted values of the final velocity compare? Compare both magnitude and direction. What are the limitations on the accuracy of your measurements and analysis?

When a moving car collides with a stationary car and they stick together, how does the final velocity depend on the initial velocity of the moving car and the masses of the cars? State your results in the most general terms supported by the data.

What conditions must be met for a system'stotal momentumto be conserved? Describe how those conditions were or were not met for the system you defined in this experiment. What conditions must be met for a system'stotal energyto be conserved? Describe how those conditions were or were not met for the system you defined in this experiment.

Which case (m_A= m_B, m_A> m_B, or m_AB) is the energy efficiency the largest? The smallest? Does this make sense? (Imagine extreme cases, such as a flea running into a truck and a truck running into a flea. In which case must the incoming "vehicle" be moving faster to satisfy your boss's assumption about initial kinetic energy? Which collision might cause more damage to the flea? To the truck?)

Can you approximate the results of this type of collision by assuming that the energy dissipated is small?

Suppose two equal mass cars traveling with equal speeds in opposite directions collide head on and stick together. What fraction of the energy is dissipated

Analysis question

Determine the velocity of the carts before and after the collision using video analysis. Treating the initial velocity as a known value, use the equations from your prediction to calculate final velocity, and compare this to your measured final velocity.

For each video, calculate the kinetic energy of the carts before and after the collision. Calculate the energy efficiency of each collision, once with the kinetic energy and once with just the cart masses using the equation found in the warm-up questions. note these methods agree? Into what other forms of energy do you think the cart's initial kinetic energy is most likely to transform?

Graph how the energy efficiency varies with mass of the initially moving cart (keeping the total mass of both carts constant). What function describes this graph?
