A spacecraft accelerates from rest: a = bt = 0.2t until a = 10.4, after which it continues at constant acceleration 10.4. Everything is in a straight line. How much time does it take to reach 10.4? (The base units are meters and seconds.) And what are the dimensions of the number b in a = bt?
A particle moves along the x-axis (units in cm). Its initial position at t=0 sec is x(0) = 15. The figure shows the graph of the particle's velocity v. The numbers are the areas of the enclosed regions. 14 Approximately where does the particle achieve its greatest positive acceleration on the interval [0,b]?

I don't understand how to do this problem. I tried taking the derivative, but that didn't give me the correct answer. I would really appreciate the help. When a 1984 Alpha Romeo Spider sports car accelerates in the x-direction at the maximum possible rate,its motion during the first 20. seconds is extremely well modeled by the simple equation vx2=(60 m2/s3)t, where t is time in seconds and vx is in m/s. In other words, the squareof teh car's velocity increases linearly with time. What is its acceleration after 3s, assuming that the car starts from rest at t=0 s?
