Zoya Ahmed Phys 30: Conservation of linear Momentum on the Collision track Aim: Determine the mass of the unknown cart using graphical analysis. photogate timers. Experimental Design: 2 cars will be collided on a collision track and velocity data will be determined using Variables: Manipulated: Change in the speed of car ! Responding: Controlled: The type of photogate timer used, the collision track used where the cars cullided Diagram/Prelab Calculations: photogate 1 photogate 2 |26 6 mi m2 (279) 1 1 Data Collection: Title: _ Change in velocity of car I V combined speed of 2 cars Speed of car 1 (m/s) V Speed of car 1 and car 2 combined (m/s) V 1 2 0 . 71 0. 31 0 . 39 0 . 10 0 . 85 0. 39 0 . 45 0 . 28 0 . 94 0 . 43 0. 87 0. 39 0 , 80 0. 38 0 .59 0. 24 0 . 5 6 0. 22 0.41 0 . 12 Analysis Questions: (answer in complete sentences on a separate sheet of paper) 1. Plot your data on graph paper and draw a line of best fit. 2. The mass of car 1 is 232-g. Using the slope of the line of best fit, determine the mass of car 2. (Hint Derive an expression using the law of conservation of momentum) (2719 ) 3. Was this an isolated system? Explain. 4. Assuming that the mass of car 2 was also-232-g, calculate the percent error. 5. Prove that the collision is inelastic. Show all work. 6. Discuss any sources of error and suggested improvements. ( No conclusion required) 1. error = exp - stol * 100 st d
