A two-stage 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:
a. the maximum speed
b. the maximum altitude
c. the height of the rocket after 20.0 seconds
d. the total time the rocket is in the air (assuming it is launched from the ground)
