A car is initially moving at 9.9 m/s in the positive x direction and accelerates at a constant acceleration of 3.4 m/s2 in the positive x direction for 6 seconds. It then immediately has an acceleration of 6.6 m/s2 in the negative x direction. After some time, its velocity is 27.6 m/s in the negative x direction. What is the average velocity for the entire trip in m/s? Indicate the negative x direction by including a negative sign but do not include a positive sign for positive answers.
