The Otto Cycle can be used to describe how an internal combustion engine works, which allows your car to run by just filling it up with gas. <span>Each of the numbers shown in the figure (1 through 6) represent one stage of the Otto cycle, or one step of the internal combustion process. The common automobile engine is called a “4 Stroke Engine” because it has 4 strokes, which are the Intake Stroke, Exhaust Stroke, Compression Stroke, and Power Stroke. The “Combustion Process” shown in the Otto Cycle in the figure occurs between Strokes 3 and 4, and the “Heat Rejection” shown in the figurea occurs between Strokes 3 and 4.</span>
Answer:
<em>The resultant velocity has a magnitude of 38.95 m/s</em>
Explanation:
<u>Vector Addition</u>
Given two vectors defined as:
The sum of the vectors is:
The magnitude of a vector can be calculated by
Where x and y are the rectangular components of the vector.
We have a plane flying due west at 34 m/s. Its velocity vector is:
The wind blows at 19 m/s south, thus:
The sum of both velocities gives the resultant velocity:
The magnitude of this velocity is:
d = 38.95 m/s
The resultant velocity has a magnitude of 38.95 m/s
