P3. A rocket of mass -1.20x10'kg is launched vertically upward from point A on the earth's surface with an initial speed v, 7.00km/s a. (12) Calculate the maximum height H of point B above the earth's surface at which the rocket will momentarily come to rest, before it starts falling back to the earth Hint: Use conservation of energy. b. (4) Determine the gravitational acceleration a at point B. c. (9) Calculate the total mechanical energy E of the rocket....
A stomp rocket is launched vertically upwards with a burst of air, when a child jumps on a flexible pillow connected to the launcher tube. Air resistance can be ignored in this question. At t=0, the rocket has just left the launcher, it has a speed of 25 m/s and the only force that it experiences is the force of gravity. "Up" is defined as the positive direction and define zero altitude as the position of the rocket at t=0....

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)...
A model rocket is launched straight upward with an initial speed of 52.3 m/s. It accelerates with a constant upward acceleration of 1.97 m/s2 until its engines stop at an altitude of 133 m. a) What is the maximum height reached by the rocket? answer: 2.99×102 m b) How long after lift off does the rocket reach its maximum height? c) How long is the rocket in the air?
A catapult launches a test rocket vertically upward from a well, giving the rocket an initial speed of 79.0 m/s at ground level. The engines then fire, and the rocket accelerates upward at 4.20 m/s2 until it reaches an altitude of 930 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)...
