Draw a best fit line/curve for each set of ds 100 Distance vs. time graph for a cart on an inclined track 90 80 70 Distance 0 .40 3 0 . 60 70 0. 80 90 1 . 0 1 1 1.2 13 1. 4 15 1: 6 17 1: 8 19- 210 0 0:20 time Data Analysis: 1. Write a relationship statement for the relationship between the distance traveled and the time. Use data from both "empty carts". 2. Write a relationship statement for the relationship between mass and "average acceleration". Use the data from both angles. (One data range statement should compare both carts and average accelerations at 50, and the second data range statement should compare both carts and average accelerations at 10.) 3. Should the acceleration be constant as the cart rolls down the ramp? Explain your answer. 4. Was the acceleration constant (within reasonable error) for each set of data? Give data from all four trials to justify your
