93. Moving Appliances Your family just had a new refrigerator delivered. The delivery man has left
and you realize that the refrigerator is not quite in
the right position, so you plan to move it several
centimeters. If the refrigerator has a mass of 180 kg
the coefficient of kinetic friction between the
bottom of the refrigerator and the floor is 0.13, and
the static coefficient of friction between these same
surfaces is 0.21, how hard do you have to push
horizontally to get the refrigerator to start moving?

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.

Well i am not very good at this but  i would be guessing 1hope i  

Motion i think. hope it
