While skiing in jackson, wyoming, your friend ben (of mass 61.5 kg) started his descent down the bunny run, 25.2 m above the bottom of the run. if he started at rest and converted all of his gravitational potential energy into kinetic energy, what is ben’s kinetic energy at the bottom of the bunny run? answer in units of j. what is his final velocity? answer in units of m/s"

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.
