Question 1 8 pts An object is moving at 9 m/s to the right at time t = 0. If this object is then moving at 3 m/s to the left at time t = 3 s, what was the object's average acceleration during this 3-second time interval? O 2 m/s2, to the left 4 m/s2, to the left O 2 m/s2, to the right O 4 m/s2, to the right
