A car starts from rest and accelerates at 3.0 m /s? for 2.0 seconds. It then continues at a constant velocity for another 3.0 seconds before decelerating uniformly for 2.0 seconds to rest. Which of the following graphs of velocity vs. time best fits the given description of the motion (4 marks)? Onone of the provided graphs is correct The average The average velocity over the first 5.0 seconds is (2 marks) The average acceleration over the entire described motion is (2 marks) acceleration over the the last 5.0 seconds is (2 marks) A car starts from rest and accelerates at 3.0 m /s? for 2.0 seconds.
