Lab 3 Analysis (This replaces section III in pp. 3-10 through 3-13 of the Study Guide.) III. Analysis A. Elastic collision, equal masses 1. Draw a line connecting the landing points of the projectile and target for each of your collisions. Ideally the midpoint of each line should be at the same point—the location of the center of mass (CM) of the two balls when they land. 2. Since the fall time is always the same, the horizontal displacements on your data sheet are proportional to the horizontal velocities. Draw a vector arrow to represent the initial velocity of the projectile ( i v G ) and the velocity of the CM ( CM v G ). Choose one collision and draw the velocity vectors of the projectile and target after the collision ( and vv G G ). See Figure 1. Figure 1 . Actual data for the equal mass elastic collision. Vector arrows have been drawn to represent the initial velocity of the projectile with no collision ( i v G ), the velocity of the target after a (nearly) head-on collision ( head-on v G ), the velocity of the center of mass ( CM v G ), and the velocities of target and projectile for collision #3 ( and GG ).
