- Calculate the initial total momentum for station 1 or 7 (be careful with signs!). Show your setup. Calculate the final total momentum for station 1 or 7 (be careful with signs!). Show your setup.

Final total momentum:

- For station 1 or 7, was momentum conserved? Support your answer. (If total final momentum is within 20% of the total initial momentum, momentum was conserved.) Example: your initial momentum was ten. 20% of that amount is 2. If your final momentum falls within the range of 8 to 12, you can consider that momentum was conserved.

- For station 2 (or 5), calculate the initial momentum of the cart. Show your set up. Calculate the final momentum of the cart. Show your setup.

Final momentum of the cart:

- For station 2 (or 5), was momentum conserved? Support your answer. (If total final momentum is within 20% of the total initial momentum, momentum was conserved.)

- For station 3 (or 6), calculate the initial momentum of cart A. Show your set up. Calculate the final momentum of carts A/B. Show your setup.

- For station 3 (or 6), was momentum conserved? Support your answer. (If total final momentum is within 20% of the total initial momentum, momentum was conserved.)

- For station 4, calculate the initial momentum of carts A and B. Show your setup. Calculate the final momentum of carts A and B. Show your setup.
Initial momentum of the carts:

Final momentum of cart B:

- Calculate the final total momentum for station 4 (be careful with signs!). Show your setup.
Final total momentum:

- For station 4, was momentum conserved? Support your answer. (If total final momentum is within 20% of the total initial momentum, momentum was conserved.)

- Why did the slope of your graphs give you speed? What must you do to make this speed a velocity?

- State one systematic and one random error that you think may have caused there to be a difference between the initial and the final momentum for each procedure. Identify each as to type of error.

- By colliding the carts off of a strong magnetic field, we approximated an elastic collision. The other stations represented inelastic collisions.
Is momentum conserved in an elastic collisions? In an inelastic collisions?

Conclusion: In your conclusion, answer the purpose in complete sentences.
State which station gave the best results. Briefly state if you felt your lab supported momentum's conservation in elastic and inelastic collisions.
