Using Velocity Data to Approximate Acceleration
Problem Statement:
The velocity of a car was recorded at several time intervals. The table containing this data can be viewed in the initial prompt. Plot the data points on the grid with velocity on the y-axis and time on the x-axis. Then determine which of the three lines best fits with the data. Then, use the line to approximate the acceleration of the car during this interval. Round your answer for acceleration to the nearest thousandth.
