Figure Q2.24 shows a motion diagram with the clock reading (in seconds) shown at each position. From t = 9 s to t = 15 s the object is at the same position. After that, it returns along the same track. The positions of the dots for t ≥ 16 s are offset for clarity. Which graph best represents the object's velocity?

A runner hopes to complete the 9.9 km run in less than 30.2 min. After running at constant speed for exactly 27.1 min, there are still 1.2 km to go. The runner must then accelerate at 0.21 m/s2 for how many seconds in order to achieve the desired time? Your answer must include two digits after the decimal point and maximum of 5% of error is accepted in your answer.
