Question

A car travels in a straight line for 1 hour. Its velocity v in miles per hour at six-minute intervals is shown in the table. (a) Produce a reasonable graph of the velocity function v by graphing these points and connecting them with a smooth curve. (b) Find the open intervals over which the acceleration a is positive. (c) Find the average acceleration of the car (in miles per hour per hour) over the interval [0, 0.4]. (d) Approximate the acceleration at t = 0.8.
