1. The problem statement, all variables and given/known data using the diagram found at this link: http:/www.physics.uoguelph.ca/phyjlh/1020/Asst_1/asst1_q1v.jpg" a) Plot a graph which shows that the acceleration is constant within the errors of measurement. b) What is the acceleration of the car? c) What was the velocity of the car at t = 0? d) If the acceleration remains constant over the next 5 seconds what will be the velocity of the car at t = 9s? e) What will be the position of the car at the time given in Part d? 2. Relevant equations v=d/t , a = v/t 3. The attempt at a solution so far I've really only tried part a) and I just can't seem to find the answer or any relevant help. What I have done is I have used the 25 m calibration to derive a 1 m = 0.372 cm scale for the graph. after doing ths I have measure all the distances at every 1 s interval. The measurements I have: 0.91 cm = 0.335 m (t=1 s) ; 2.75 cm = 1.02 m (t=2) ; 4.69 cm = 1.74 m (t=3) ; 6.45 cm = 2.40 m (t=4). I have found velocities for all of these values: t 1 = 0.335 m/s ; t 2 = 0.510 m/s ; t 3 = 0.580 m/s ; t 4 = 0.600 m/s First of all, are these values even correct? Because when I plot them I get nothing close to a linear graph. Are my errors of measurement that off? Ultimately, I'm just really confused and need some help starting this problem correctly. I feel that once I have a grasp on how to go about doing part a) correctly everything would fall into place. This question is worth 2% of my final mark so I'm kind of freaking out. Any help is appreciated.
