Unformatted text preview: Table 2. Leave your first fit there. Highlighting 10 points on your graph immediately after the collision, determine the velocity and associated experimental uncertainty after the collision. Enter your results in Table 2. Print your graph with both fits displayed and a title by going to Logger Pro choose then . Physics 1020 Laboratory #5 Momentum and Impulse Part III: Conservation of Momentum The two cart system. Physics 1020 Laboratory #5 Momentum and Impulse The System In this part you must choose the system as the two carts as illustrated. system=cart1 + cart2 v1i v2i 0 m1 m2 initial position system=cart1 + cart2 vf m1 m2 final position QUESTION 2: Using the notation from the diagram, write the equation for the total momentum of the system before the collision psys i . Write the equation for the total momentum of the system after the collision psys f . QUESTION 3: After the cart is pushed, is there a net external force acting on this system at any point between the initial position of cart 1 and the final position? (Assume friction is negligible.) QUESTION 4: Do you expect v f to be greater than or less than vi ? Explain why. Physics 1020 Laboratory #5 Momentum and Impulse Momentum Conserved? QUESTION 5: Using the equations from Question 2, determine the total momentum both before, psys i, and after, psys f , the collision for this system. Remember to calculate experimental uncertainties and then write the result in the form p p . [You may want to review the section on experimental uncertainties in the Making Measurement in Physics document.] QUESTION 6: Is the momentum before the collision equal to the momentum after the collision within the experimental uncertainty? Is this an expected result given the answer to Question 3? Explain. QUESTION 7: Calculate the impulse for this system. (Again, remember to calculate the experimental uncertainty and write the impulse in the correct form.) Is it equal to zero within experimental uncertainty? QUESTION 8: Are the answers...
