I'm suppose to draw a v-t and a-t graph from a given x-t graph. Here is the x-t graph and my attemps on the other two graphs from the x-t one. Howeverr 1. My teacher said that these graphs are discontinuous? Because I often see in littetaure that they drag "a vertical line" whenever something takes a jump, but it is discontinuous in the v-t graph right? 2. If it is discontinuous, and no vertical line down, If i was given the v-t graph and wanted to do a x-t rgaph. Then I would "imagine" a vertical line right? To calculate an area ? 3. Are these 2 graphs correct or what could be improved/ Whats wrong?
