I ea You are looking at a data table containing velocity and acceleration data for a moving object. There is a range of times for which both the velocity and the acceleration of the object are negative. 7) Give an example of a real-life situation that could produce this data. Explain your answer.

The police car immediately begins to accelerate to the south at 1.80 m/sz. 9) At what time I does the police car catch up with the Speeder
