Guide Questions: 1. Does the mass of the ball affect its flight duration? Why or why not? 2. What other factors affect the flight duration of each ball? Discuss the effects of these factors. 3. Are the results of the experiments conclusive? Are the experimental results consistent with the prediction/ calculations using the Kinematic Equations? 4. What is the significance of the 3-m radius on the ground? 5. A sky-diver jumps out of a hovering helicopter. A few seconds later, another sky diver jumps out, and they both fall along the same vertical line. Ignore air resistance, so that both shall fall with same acceleration. Does the difference in their speeds stay the same all throughout the fall? Does the vertical distance between them stay the same throughout the fall? Explain thoroughly.
