1. The problem statement, all variables and given/known data 1. Plot the following motion of an object on a d-t graph. Position (m north of the CN tower) Time (s) 0 0 50 5 150 10 300 15 500 20 750 25 1050 30 1. Describe the motion of the object. 2. Is the object accelerating at a uniform rate? To find out, add a third column to the chart above and calculate the average velocity during each interval. 3. Plot velocity vs time now on another graph. What do you notice? Does the object exhibit uniform acceleration? Explain how you know. 4. Calculate the acceleration of the motion. 5. Calculate the area under the velocity-time graph. Compare your answer to the value you expected to obtain. Explain your comparison. 2. Relevant equations 3. The attempt at a solution Since there's charts and graphs involved I have my answer in html format here. http://www.freewebs.com/dazed42/physics.htm [Broken] The problem is, the area under the velocity-time graph is supposed to give the displacement. I know the displacement is 1050m, but the area of my velocity-time graph yields only 900. What gives?
