8. A woman driving her car approaches an intersection and begins 10 accelerate just as the traffic light turns green. The graph shows her velocity as a function of time described by the equation MA =2r^2 -8t + 10 (a) Use calculus to find her instantaneous acceleration at 1= 3.0 s. (b) Use calculus to find the area under the curve to see how far she traveled between 1 = Os and i = 5.0 s
