Document Summary

Ch 12 reference movement - also figure 1. 2 pg 328. 4 questions: divide the high jump task into two phases: the first is when the jumper is on the ground and approaching the bar, the second is when the jumper is airborne. Draw a stick figure" that represents the position of the jumper at, a) the instant of takeoff, and b) the point of maximum height of the overall center of mass. Cg follows prescribed parabolic path (after take off) Gravity reduces vertical velocity after take off (continues till at 0) Slow takeoff velocity = air-drag force very little compared to body-weight force. Jumper need enough horizontal velocity to move over the bar. Air-resistance force (strong head wind) - this will decrease the horizontal velocity. Need to increase horizontal resistance (decrease if there is a strong tail wind) Rotary + linear motion caused by eccentric force applied to diver by.
