Investigation 2.1 Now set up the experiment for an elastic collision. First use two gliders of equal mass with an elastic bumper sticker on one side of each glider. How do you have to set up the gliders and photogates to get the initial and final speeds for each glider? / gudin at it begrimmarch Push the gliders so that they move slowly. You will have to record the initial time for each glider and then move the memory switch to pre- and post- collision times. In order to obtain the post collision time, you will have to subtract the pre-collision time. Show your work and record your data below. W/ = 0 076/0 6-26 -0.8541 VE = 0 096/ (0 5342 - O RaRe) = 0.80 +5
