1. Measure the mass of the cart as accurately as possible. 2. Using the caliper measure the height of the large heaviest block After that measure the height of the combination of this bloc.. and each or the elevation blocks Measure the distance between track JUppurts Using trigonometry soive for the angies of include between the air track and the table. Confirm that the angle measurewe: to are connect by checking with a lab instructor A. Start up the appopriate computer sort are routine for the interface . hich is connected to a photogate ino. ito my the pulley . place the first mass on the descending mass hanger. measure a..a record the total J. Make sure that the descending .lass is come ted with the stanly to the carta a 15 gummy O. er the pulley 7. Pull the art bac.. until the rass hanger is almost at the pulley start the data collection and release Note the first fave trials are with the air track level (cero degree angle) 8. Stop the data collection once the descending mass hits the ground this awes.'t have to be exactj. Y. Represented on the computer should be a graph of velocity (m/s) v. time (s). On this graph should be a linear line which ascends then may become rough The linear portion of the graph is what should be analyzed to find the correct data The rough part represents when. the mass hit the floor. Grab the linear part of the _raph which need. to be analy. ea by highlighting it with the lett click on the i wuse and dragging a bo . around thi. region Jbtal. the statistical slope of the line to find the Kinematical acceleration and the standard deviation Mak. sure w cul-ct at Least five significant digits for the kin_matical acceleration 1v. Kepeat this sequence (steps 6-1J) adding additional mas. for each different tual, > thals total. Remember to measure each total mass (including the hanger) and record it on the data sheet be.ore conducting each trial. 11 for trials o thru 10 use the same mass a. trial 5 and repeat the sequence (steps 7 -10), now changing the lacknation angle by using the combinations of the elevation blocks for each toal Note, these trial. will not have a zero degree angle but will have a constant mass. 12. Now it is necessary to calculate the dynamical acceleration using the proper equation The values for the dynamical acceleration ( the acceleration. calculated using Newton's Second Law) should compare to the values obtained for the kinematic acceleration (the actual physical resultant acceleration) 13. Using your dynamical acceleration calculate the net force ou the cart. 14. Graph 1 excel the kinematic acceleration vs the net force This should result in a linear relationship
