Please help with the bottom questions! I am also having trouble calculating the velocity for the second part.

Report Sheet Uniform and Accelerated Motion Part 1: Uniform motion Time (sec) Distance (cm) 0. 243 20 0. 389 40 0.597 60 0. 749 80 0.922 100 1.217 120 Include a file called uniform motion.cmbl showing a graph of time on the x-axis vs. distance on the y-axis. Part 2: Accelerated motion Distance (cm) Time (s) Distance (cm) Time (s) Speed (m/s) on ramp on ramp on level on level on level surface surface surface 0 0 O O 0 20 0.513 (00.0 1.4 73 67.89 40 100 . 0 0.962 104 60 1. 044 100. 0 O. 709 141 1.15- 6 100.0 0. 6041 156 1:312 108 0 0.513 195 Include a file called accelerated motion.cmbl with graphs of distance on the y- axis vs. time on the x-axis and velocity on the y-axis vs. time on the x-axis.Questions 1) If the speed is constant for Part 1: Uniform Motion, then d = do + vt. Based on the parameters of the best linear fit to the data, y = mx+b, what are the values of do and v for your marble? 2) If the acceleration is constant for Part 2: Accelerated Motion, then v = vo + at. Based on the parameters of the best linear fit to the data, y = mx+b, what are the values of vo and a for your marble? 3) Since the marble always started from rest, what value of vo would you expect as the intercept for Question 2, and how close did you come to it? 4) What is the value of the constant acceleration based on the a term of the best fit to a quadratic of the data on the first graph? 5) How do the values for the acceleration from the two plots compare? Are they close? Justify your response
