SUMMARY

This discussion focuses on the application of physics concepts related to velocity, acceleration, and gravity, specifically in the context of solving problems involving the Concorde's landing speed. The key points include converting the cruising speed of 2.30 x 10³ km/h into meters per second and understanding the relationship between initial velocity, final velocity, and deceleration of 5.80 m/s². The discussion emphasizes the importance of using the correct formula to connect the provided data without introducing unnecessary variables.

PREREQUISITES
  • Understanding of basic physics concepts such as velocity and acceleration
  • Familiarity with the formula for calculating distance using initial velocity, final velocity, and acceleration
  • Ability to convert units, specifically from kilometers per hour to meters per second
  • Knowledge of the concept of deceleration and its application in motion problems
NEXT STEPS
  • Learn how to convert km/h to m/s accurately
  • Study the kinematic equations for uniformly accelerated motion
  • Practice solving physics problems involving deceleration and distance
  • Explore real-world applications of physics in aviation and other fields
USEFUL FOR

Students studying physics, educators teaching motion concepts, and anyone interested in understanding the principles of velocity and acceleration in practical scenarios.

In physics we are studying velocity acceleration and gravity. Either i am stupid or am not understanding this, but i just can't seem to understand the material. for example i don't know which formula to use for which story problem, for example(Please do not answer the problem) With a cruising speed of 2.30 X 10 to the third km/h, the french supersonic passenger jet concorde is the fastest commercial airplane. Suppose the landing speed is 20.0 precent of the cruising speed. Over what distance(meters) does the plane travel to a complete stop if its deceleration has a magnitude of 5.80m/s squared

I know that i have to get the km/h into meters per second, but i don't know how to solve it.

Any help or tips would be greatly appreciatied

To solve any problem, at least in the initial stages of education, look at what data you are supplied with, then use the appropriate formula that connects these data. And don't bring in new variables unncessarily.

Back to the problem...you are provided with the initial velocity ("landing speed") of the aircraft, the final velocity, and the decelaration ("negative accelaration"). Now, what formula can you use to find the distance traveled given the above information?
