Some latest academics question and answer inquired students to assert what they presume is the most crucial important thing for a student to do to be able to obtain success. One that response stood out from the rest was practice. Persons who are certainly successful do not become successful by being born. They work hard and dedication their lives to succeeding. This is how you can get your goals. in this article, some question and answer examples that you might possibly benefit from to expand your knowledge and gain insight that will help you to maintain your school studies.
Question:
A helicopter is traveling at 86.0 km/h at an angle of 35° to the ground. What is the value of Ax? Round your answer to the nearest tenth. km/h
Answer:
Answer: 70.5 km/h
Justification:
The question is not clearly stated but it seems you are asking for the x – component of the velocity of the helicopter.
You can find the x and y – components of the velocity using the trigonometric ratios sine and cosine.
The sine ratio relates the y-component and the velocity by:
sin(angle) = y-component of velocity / velocity
The cosine ratio related the x-component and the velocity by:
cos(angle) = x-component of velocity / velocity.
Since you have the angle and the velocity and are asked by the x-component of the velocity, you need to use the cosine ratio:
cos(35°)= x-component / 86.0 km/h
=> x -component = 86.0 km/h * cos(35°) = 70.5 km/h
From the answer and question examples above, hopefully, they can assist the student solve the question they had been looking for and keep in mind of everything stated in the answer above. You can potentially then have a discussion with your classmate and continue the school learning by studying the problem to one another.
