A sounding rocket, initially at rest on the ground, accelerates vertically.
It accelerates uniformly until it reaches a speed of 800 m/s800\text{ m/s}800 m/s after 40 s40\text{ s}40 s.
After this period of uniform acceleration, the rocket engine cuts out. During the next 120 s120\text{ s}120 s, the upward speed of the rocket decreases uniformly to zero.
Describe the key features of the speed-time graph for the rocket for the first 160 s160\text{ s}160 s of its flight, including the coordinates (t,v)(t, v)(t,v) of the start, peak, and end points.
Calculate the acceleration of the rocket during the first 40 s40\text{ s}40 s.
Determine the maximum height reached by the rocket at the end of the 160 s160\text{ s}160 s flight.
