. A race car moves such that its position fits the relationship
x = (5.0 m/s)t + (0.75 m/s3)t3
where x is measured in meters and in t in seconds. (a) Plot a graph of the car’s position versus time. (b) Determine the instantaneous velocity of the car at t= 4.0 s, using time intervals of 0.40 s, 0.20 s, and 0.10s. (c) Compare the average velocity during the first 4.0 with the results of part (b).
