Now let’s see if your prediction agrees with the experimental results. there isn’t any data at y = -3.5 m, so you’ll need to interpolate by zooming in on the relationship between y velocity (vy) and y displacement. you’ll use tracker’s data tool to with this analysis. follow these steps: change the vy versus t graph to a vy versus y graph. (click the t label on the horizontal axis and select y: position y-component from the menu.) it’s a little hard to see what’s going on with this graph at y = -3.5, so zoom in. double-click on the graph to open it up in the data tool. put your cursor on the point where the graph line intersects y = -3.5. click and hold to read the vy at that point (shown in a yellow box). what’s the interpolated graph value of vy at y = -3.5? comment on how well this value agrees with the value of vy that you calculated in part a of this activity. make a hypothesis about any notable difference.
