As discussed in Unit 1A, we can learn a lot from the velocity versus time graph of an object's motion. Consider the following graph of a cart's motion and answer

the questions below. At t=0, was the cart at rest? Is the cart getting faster during the 6s time interval? What does the slope of the line represent? What does the area under the curve represent? What is the slope of the cart during the 6s interval? What is the area under the curve of the cart during the 6s interval?
