e) None of the above. sele 13 When a 1984 Alfa Romeo Spider sports car accelerates in the x-direction at the maximum Þóssible rate, its motion during the first 20. seconds is extremely well modeled by the simple equation vx = (60 m/s)t, where t is time in seconds and vz is in m/s. In other words, the square of the car's velocity increases linearly with time.
