Description: A car starts from rest at $s = 0$ and is subjected to an acceleration defined by the following $a$–$s$ graph: - $a = 12$ ft/s² for $0 \le s \le 300$ ft - $a = -0.04s + 24$ ft/s² for $300 \le s \le 450$ ft (a linear decrease from 12 ft/s² at $s = 300$ ft to 6 ft/s² at $s = 450$ ft) Draw the $v$–$s$ graph and determine the time needed to travel 200 ft.
