Question

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 (stage D). The parachute forces the rocket to descend at a constant (vertical) speed of 11 ms-1 but during its descent wind blows towards the West with horizontal speed 18 ms-1 until it lands on the ground (stage E). Find:

a) for how long the rocket was ascending without its engine (in seconds)

b) the maximum height of the rocket (in meters)

c) What was the horizontal displacement of the rocket from the time the parachute opened until it landed (in meters)?
