The rocket is launched at 36° with the ground (stage A), from rest towards the East. The rocket engine provides a constant net acceleration of 4.1 ms-2 and burns for 8.6 s (stage B). During this stage (i.e. AB) the rocket travels in a straight-line. At the end of stage B the engine shuts off and rocket starts moving as a typical projectile. After reaching its maximum height (stage C), it drops for 82 m and then a parachute opens...
