A two­stage rocket accelerates from rest at +3.57 m/s/s for 6.82 seconds. It then accelerates at +2.98 m/s/s for another 5.90 seconds. After the second stage, it enters into a state of free fall. Determine:

• the maximum speed • the maximum altitude • the height of the rocket after 20.0 seconds • the total time the rocket is in the air (assuming it is launched from the ground)
