Description: A two-stage rocket is fired vertically from rest at $s = 0$. During Stage A ($0 \leq t \leq 30$ s) the rocket has a constant acceleration of $15 \text{ m/s}^2$. At $t = 30$ s, Stage A burns out and Stage B ignites with a constant acceleration of $70 \text{ m/s}^2$. Determine and describe the $v$–$t$ and $s$–$t$ graphs describing the motion for $0 \leq t \leq 60$ s.
