An automobile moves forward and backward on a straight highway.The graph shows the velocity of this automobile as a function of time.
What is the acceleration of the automobile at t = 4 s? (Round to two significant digits.)
a = change in velocity / time
I said the acceleration was zero, because the automobile would be stopped at t = 4 s. This is wrong, however.
