2. A car moves along anx-axis through a distance of 900 m, starting from rest (at r-0 m) and stopping at x-900 m. It accelerates at +6 m/s through first 10 s of time. Then, through the remaining part of that distance, it slows down with constant acceleration until it stops. What are the: (a) car's maximum speed? (b) distance traveled during the first 10 s of time? (c) acceleration through the remaining part of the distance? (d) time elapsed...
