Ahooke's law spring is mounted horizontally over a frictionless surface. the spring is then compressed a distance d and is used to launch a mass m along the frictionless surface. what compression of the spring would result in the mass attaining double the speed received in the above situation? a. 1.73 db. 1.41 dc. 4.00 dd. 2.00 da hooke's law spring is compressed a distance d and is used to launch a particle of mass m vertically to a height h above its starting position. under double the compression, the spring is now used to launch a particle of mass 2m. how high does the second mass rise above its starting position? a. 1 hb. 2 hc. 3 hd. 4 h

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.

Milliseconds. . . . . .

Iwas going to ask that quesytion  sorry dude i dont  know : (    : /
