2. "A student holds a thin aluminum pie pan horizontally 2 m above the ground and releases it. Using a motion detector, she obtains the graph shown in Figure P3.12. Based on her measurements, (a) draw force dia- grams for the pie pan at times 0.05 s, 0.3 s, and 0.7 s, and (b) estimate the distance that the pan travels once it reaches constant speed.
