1) Pretend you are the new Track & Field coach for your school; you want to apply what you learned in the Biomechanics course to help your long jump athletes improve. Unfortunately, the Track & Field program does not have a lot of money so the only equipment you have is a stopwatch (to measure the athlete's time of flight), a tape measure (to measure the length of the jump), and a calculator. In a practice jump, one of your athletes was in the air for 1 second and recorded a jump of 8m. Assumptions: The athlete's center of gravity undergoes projectile motion during the long jump Air resistance is negligible and the athlete's center of gravity has the same height at launch (i.e., takeoff) and landing Based on the above assumptions: for a given take-off velocity magnitude, the maximum horizontal range of motion is achieved when the takeoff angle is 45° Should the athlete increase or decrease his angle of release (i.e., takeoff angle) to improve his performance? (Answer: Should increase) а. b. For the takeoff speed that the athlete generated, what is his best possible jump? (Answer: 8.9) С. Do you think the assumptions above valid? Why or why not?
