Question

Calculus Workbook 2. The displacement of a car from its starting point after \(t\) hours is given by \(d = f(t)\) miles; a graph of the function \(f\) is shown to the right. (a) Estimate the time interval(s) on which the car has positive accelera- tion, and explain how you identified them. 37 d 400 300 200 100 1 2 3 4 5 6 7 8 \(t\) (b) Estimate the time interval(s) on which the car has negative acceleration, and explain how you identified them. (c) During the first 5 hours of its journey, estimate when the car has its minimum velocity.
