How far off is your vertical acceleration from the expected value? Give a percentage difference. Explain your answers/show calculations. (5 points) Answer here Some Comments: The expected acceleration for free fall, at the location where the experiment is performed and in the absence of air resistance, is g = 9.80 m/s'. One reason for the difference from the expected value is the effect of the air resistance that increases d) Plot y-Position vs Time using the scattered mode. Add a trendline as suggested by with velocity (this is a topic you'll learn a bit later in the course). The air resistance opposes the conclusions drawn from the y-velocity graph. Show the trendline equation on the motion of the ball during the flight, thus decreasing the vertical acceleration and chart. (5 points) generating a horizontal deceleration. If your x-velocity data shows a bit of downtrend, and your vertical acceleration is smaller than g, it could be the effect of the air resistance.
