Suppose you are navigating a spacecraft far from other objects. The mass of the spacecraft is 3.2 × 104 kg (about 32 tons). The rocket engines are shut off, and you're coasting along with a constant velocity of <0, 20, 0> km/s. As you pass the location <4, 2, 0> km you briefly fire side thruster rockets, so that your spacecraft experiences a net force of <9 × 105, 0, 0> N for 20.0 s. The ejected gases have a mass that is small compared to the mass of the spacecraft. You then continue coasting with the rocket engines turned off. Where are you an hour later? (Think about what approximations or simplifying assumptions you made in your analysis. Also think about the choice of system: what are the surroundings that exert external forces on your system?)

Suppose you are navigating a spacecraft far from other objects. The mass of the spacecraft is 2.3 x 104 kg (about 23 tons). The rocket engines are shut off, and you're coasting along with a constant velocity of <0, 28, 0> km/s. As you pass the location <2, 4,0 km you briefly fire side thruster rockets, so that your spacecraft experiences a net force of <2 x 105, 0, 0> N for 23.5 s. The ejected gases have a mass...
.P20 Suppose that you are navigating a spacecraft far from other objects. The mass of the spacecraft is 1.5 x 10 kg (about 150 tons). The rocket engines are shut off, and you're coasting along with a constant velocity of (0,20,0) km/s. As you pass the location (12,15,0) km you briefly fire side-thruster rockets, so that your spacecraft experiences a net force of (6 x 10,0,0) N for 20 s. After turning off the thrusters, you then continue coasting with...
box in answer please 18. 0/10 points I Previous Answers SerPSET9 13.P065 My Notes Ask Your Teacl As an astronaut, you observe a small planet to be spherical. After landing on the planet, you set of, walking always straight ahead, and find yourself returning to your spacecraft from the opposite side after completing a lap of 24.2 km. You hold a hammer and a falcon feather at a height of 1.37 m, release them, and Determine the mass of the...
Before leaving Alpha Centauri, you change from the shuttle to a light speed interstellar cruiser and head out deep into the galaxy to visit another binary star system - but this one is composed of dead stars! To occupy your waking travel time by reading about this star system in the "Outer Space Tourbook": Stars spend most of their lifetimes undergoing nuclear fusion in their cores, which is why they give off so much light. However, when the material necessary...
Think about your personal budget. How different do you think it is from a company budget? Understanding the different components outlined in a company budget, in addition to the order of completion, helps a business owner, professional, and/or student set reasonable and attainable goals. Budgeting is considered a benchmark document that is pertinent to setting goals and answering questions. Read the following scenario and complete the questions posed below. Scenario Don Flowers, owner of VGTBLS (pronounced Vegetables), has three food...
