Answer:
T = 15 kN
F = 23.33 kN
Explanation:
Given the data in the question,
We apply the impulse momentum principle on the total system,
mv₁ + ∑
= mv₂
we substitute
[50 + 3(30)]×10³ × 0 + FΔt = [50 + 3(30)]×10³ × ( 45 × 1000 / 3600 )
F( 75 - 0 ) = 1.75 × 10⁶
The resultant frictional tractive force F is will then be;
F = 1.75 × 10⁶ / 75
F = 23333.33 N
F = 23.33 kN
Applying the impulse momentum principle on the three cars;
mv₁ + ∑ = mv₂
[3(30)]×10³ × 0 + FΔt = [3(30)]×10³ × ( 45 × 1000 / 3600 )
F(75-0) = 1.125 × 10⁶
The force T developed is then;
T = 1.125 × 10⁶ / 75
T = 15000 N
T = 15 kN
Answer: the answer is plagiarism.
Explanation: Plagiarism is the act of taking credit from someone else's works or ideas, without acknowledging the author. <u>Conflict of interest</u> occurs when an employee has <u>interests that are at odds to each other</u>, which isn't shown at the excerpt given in the exercise. <u>Fabrication</u> is the <u>creation of intellectual property</u>, also not shown in the exercise, and <u>falsification</u> is the <u>creation of a scientific hypothesis</u> that <u>cannot be verified</u> by lack of practical evidence, which is not the case described as well.
