Explain your answers/show calculations. (5 points) Answer hereSome 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 my'sl. One reason for the difference from the expected value is the effect of the air resistance that increases with velocity (this is a topic: you'll learn a bit later in the course]. The air resistance opposes the motion of the ball during the flight, thus decreasing the vertical occeierotion and generating o horizontoi deceierotion. If your xvelocity data shows a bit of downtrend, and your vertical acceleration is smaller than g, it could be the effect of the air resistance. of course, there is always the measuring errors; They can change the results either away, and could very easily bury the small changes created by air resistance. Conclusions Discuss whether your results for the horizontal and vertical components of the ball's motion agree {or disagree!] with the projectile motion expectations.
