In his 1865 science fiction novel From the Earth to the
Moon, Jules Verne described how three astronauts are shot to
the Moon by means of a huge gun. According to Verne, the aluminum
capsule containing the astronauts is accelerated by ignition of
nitrocellulose to a speed of 11 km/s along the gun barrel's length
of 220 m. (a) In g units, what is the
average acceleration of the capsule and astronauts in the gun
barrel? (b) Is that acceleration...

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 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)...

A catapult launches a test rocket vertically upward from a well, giving the rocket an initial speed of 80.4 m/s at ground level. The engines then fire, and the rocket accelerates upward at 3.90 m/s2until it reaches an altitude of 1090 m. At that point its engines fail, and the rocket goes into free fall, with an acceleration of −9.80 m/s2.

A 170 kg rocket is moving radially outward from the earth at an altitude of 180 km above the surface with a velocity of 3.5 km/sec. At this point, its final stage engine shuts off. 1) Ignoring any minor air resistance, what is the rocket's velocity 780 km above the surface of the earth?"; m/sec 2) Again ignoring any minor air resistance, what is the rocket's velocity 780 km above the surface of the earth if its mass were 340...

Question 3 On 21 January 2018, Rocket Lab launched a 10 500 kg rocket from the Mahia Penin- sula. It carried a 250 kg payload that included the 8 kg Humanity Star, which is like a large disco ball in size and shape. (a) On the launchpad, the rocket has a mass of 10 500 kg and produces 160 kN of vertical thrust. Assuming that the acceleration is constant and motion is in a straight line, find the speed of...

(8%) Problem 11: A student launches a small rocket which starts from rest at ground level. At a height of h- 1.85 km the rocket reaches a speed of ve 395 m/s. At that height the rocket runs out of fuel, so there is no longer any thrust propelling it. Take the positive direction to be upward in this problem.
