Problem 1-3: A vehicle enters a test section of a straight
road at s = 0 km with a speed of 60 km/hr. It then
undergoes an acceleration a, which varies with position as
shown in the adjacent figure. Determine the velocity v of the
vehicle as it passes the position s = 0.2 km. (Due: At the
beginning of the class on Thursday, Sep 14th, 2017).
