Answer #1

As the rocket has reached a height of 1.85km = 1850m before it's engine turns off. We will calculate the distance travelled after engine is turned off and add it to 1850m

distance travelled after engine is turned off =

S=2X

S 02-3952 x (-9.8) = 7960.5m 2

therefore, total height reached = 1850+7960.5

= 9.8 Km

    A catapult launches a test rocket vertically upward from a well, giving the rocket an initial speed of 80.2 m/s at ground level. The engines then fire, and the rocket accelerates upward at 4.10 m/s2 until it reaches an altitude of 1190 m. At that point its engines fail, and the rocket goes into free fall, with an acceleration of −9.80 m/s2. (You will need to consider the motion while the engine is operating and the free-fall motion separately.) (a)...

    Carlon launched a toy rocket vertically up from ground level (y = 0 m), at time t = 0.0 s. The rocket engine provides constant upward acceleration of 12.3 m/s2 during the burn phase. At the instant of engine burnout the rocket has risen to 89 m. The rocket continues to rise in unpowered flight, reaches maximum height, and falls back to the ground. The maximum height reached by the rocket is closest to:
