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.
