Question
Michael began driving a car on a straight track due north at t = 0 seconds. After 6 seconds, he stopped the car and began driving in reverse, south, for another two seconds, and then he stopped again. The graph below gives the velocity of the car, in meters per second, for the 8 seconds while Michael was driving it. From the information, you have boon given, make an argument as to whether or not Michael passed over his original starting location while he was driving in reverse. Give an expression, in terms of V(t), that would give Michael's change in position over the 8 seconds' time period he was driving.Explanation / Answer
a. Clearly, the area under the first curve is less than the area under the second curve. The area under the curve is the total distance traveled.
b. int from 0 to 8 of v(t) dt
