A student used a spreadsheet to create a computational model of the energy changes experienced by a falling 0.75-kg ball. The student entered a particular initial velocity into the model and noticed that some of the values in the velocity column were positive and some of the values were negative. In one or two sentences, make and justify a claim about the boundary conditions that would lead to this situation.
