98 points! 5 easy questions. look up luke aikins no parachute 25,000 feet airplane jump complete video on yt answer questions that follow wind resistance slows luke to 150mph. how fast is this in meters /sec? is luke still accelerating when he is falling at 150mph? explain. what is the force of wind resistance on luke once he is falling at 150mhp? if there were no wind resistance what would luke’s kinetic energy be just before he hits the net? luke was unhurt after landing in a net. how is this possible? explain how the net prevented any injury to luke. use terms like impulse, force, momentum and time.

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
