Atruck is speeding up as it travels on an interstate. the truck's momentum (in kg · m/s) is proportional to the truck's speed (in m/s). a) at some moment the truck's momentum is 48300 kg · m/s and the truck's speed is 23 m/s. at this moment, the truck's momentum (in kg · m/s) is how many times as large as the truck's speed (in m/s) b) this means that as the truck travels, the truck's momentum (in kg · m/s) is always times as large as the truck's speed (in m/s). c) if the truck is traveling at 17 m/s, what is the momentum (in kg 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.
