Activity In this activity you'll use the Data tool in Tracker. If it isn't already open, open the Tracker ball drop 1 C experiment. Part A Predict the velocity vy when y = -3.5 meters. Use the average acceleration you calculated in Activity 1. Use the formula v2 = V02 + 2ay, where v = final velocity, vp = initial velocity, a = average acceleration, and y = y displacement. (Note that vis the final velocity in the y direction: v.) V2X 15nY !! 11 lil = 9
