Jump height calculated using three different methods Impulse-Momentum Time in the Air Motion Capture Method Method Method Impulse (Ns) 130.00 Time to Peak Height (s) 0.27 s Takeoff Velocity (m/s) 1.76 m/s 2.65 m/s Jump Height (m) 0.16 m 0.36 m 0.43 m Discussion: 1. Compare the two lines on your graph. Discuss where the preparation/takeoff, flight, and landing phases take place. 2. Comment on the similarities and differences between your results. Which method do you think is the most accurate representation of jump height? 3. Discuss 1 advantage and 1 disadvantage for each of the three methods. Consider time, resources/equipment available, etc
