Aerospace engineers design, analyze, model, simulate, and test aircraft, spacecraft, satellites, missiles, and rockets. Aerospace technology also extends to many other applications of objects moving within gases or liquids. Examples are golf balls, high-speed trains, hydrofoil ships, or tall buildings in the wind. As an aerospace engineer, you might work on the Orion space mission, which plans on putting astronauts on mars by 2020. Or, you might be involved in developing a new generation of space telescopes, the source of some of our most significant cosmological discoveries. But outer space is just one of many realms to explore as an aerospace engineer. You might develop commercial airliners, military jets, or helicopters for our airways. And getting even more down-to-earth, you could design the latest ground and sea transportation, including high-speed trains, racing cars, or deep-sea vessels that explore life at the bottom of the ocean.
I am just questing to point a ok ok ok this might not be right
Answer:
Attached below
Explanation:
a) combustion gases in a cylinder during the power stroke is A closed system
b) Combustion gases in a cylinder during the exhaust stroke is an Open system
c) A balloon exhausting air is an Open system
d) It is a system
e) This is a control volume
Attached below is the sketch of the following situations
Answer: a) -5 ft/s²
B) 4.5 ft
Explanation: Radius= 250ft
Velocity V = 3(t-t²)ft/s
A). When t= 3 s, the acceleration is
dv/dt = 1-2t
dv/dt = 1- 2(3)
= 1-6
= -5 ft/s²
B. How far it traveled in 3 sec
Distance= 3t²/2 -t³/3 ft
Substituting 3
Distance = 27/2 - 9
= 13.5 - 9
= 4.5 ft
