Part C Next, you'll compare your model for the man with your model for a boy sliding on the same sled along the same path. Keep the
first Tracker experiment open, but also open this Tracker experiment: Ice Slide 1 modele.
From this file, select the point mass model boy and repeat the procedure you used to create the dynamic model for the man.
Once again, use the initial values for time t = 0.20 seconds.
Try different values of the coefficient of friction and come up with a model that matches the motion of the child. Once again,
modify the value of mk to get as close as you can to matching the boy's observed position for the entire slide.
Once you're satisfied with your model for the boy, record your model values in the table below.

Full change in the electric plus system

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.
