[Answered] What is a scale on a map?

[Answered] An aircraft has a liftoff speed of 33 m/s. What minimum constant acceleration does this require if the aircraft is to be airborne after a take-off run of 240 m? Show your work.

[Answered] How do you work this problem?

[Answered] Solve for \( t \): \[ a = \frac{vf - vi}{t} \] Solve for \( vi \): \[ a = \frac{vf - vi}{t} \] Solve for \( vf \): \[ a = \frac{vf - vi}{t} \]

[Answered] For this assessment, you will be taking Newton’s laws and describing how they are illustrated in a specific event. You only need to choose one of the options provided. Once you select the option, you will describe in detail how this option illustrates each of Newton’s three laws of motion. **Option One:** Amusement parks are a great place to see Newton's laws of motion in action. Choose your favorite ride and describe the parts of the ride that illustrate each of Newton's laws of motion. You are only required to give a written description; however, if you would like, you may draw and label a picture in addition to the paragraph explanation. Please be sure to look at the rubric to see exactly what you are expected to include! **Option Two:** Understanding the laws of motion can enhance performance in sport activities. Choose your favorite sport and describe where players use Newton’s three laws of motion to be successful. You are only required to give a written description; however, if you would like, you may draw and label a picture in addition to the paragraph explanation. Please be sure to look at the rubric to see exactly what you are expected to include! **Option Three:** In the United States, car accidents are the leading cause of death for teenagers. Wearing seat belts helps save lives. Describe how Newton’s three laws of motion are used in testing the safety of our automobiles. You are only required to give a written description; however, if you would like, you may draw and label a picture in addition to the paragraph explanation. Please be sure to look at the rubric to see exactly what you are expected to include!
