In summary, the conversation is about a problem in Mechanics, specifically finding the velocity and position of a particle under the influence of a given force function. The conversation mentions using Newton's Second Law and integrating the problem to find the solutions. It also suggests posting similar problems in the Introductory Physics subforum in the future.

I am just starting out in Mechanics at my University. (Mechanincs is also known as statics and dynamics). I am having trouble working (what should be a simple) problem.

Here is the problem:

Find the velocity X(with 1 dot above the x) and the position X as a functin of the time t for a particle of mass m, which starts from rest at x=0 and t=0, subject to the following force functions:

Fx=f0+ct
where F0 and c are positive constants



Any help is greatly appreciated. :eek: :confused:

Think Newton's second law;

[tex]F = ma = m\ddot{x}[/tex]

Thanks, I wass thinking of Newton's 2nd, but you also have to integrate problem, correct?

Thanks for any help and Newton's confirmation :)

Yes, you need to substitute the given expression in the equation for Newton's Second and integrate it to get the required answers.

Please post similar problems under the Introductory Physics subforum next time.
 

Related to Solving Mechanics Problem: Velocity X and Position X Function of Time t

What is velocity and position in mechanics?

Velocity is the rate of change of an object's position with respect to time. It is a vector quantity that includes both magnitude (speed) and direction. Position is the location of an object in space, typically measured in relation to a reference point.

How do you find velocity and position in a function of time?

To find velocity and position in a function of time, you need to use the equations of motion. Velocity can be calculated by taking the derivative of the position function with respect to time. Position can be found by integrating the velocity function with respect to time.

What is the importance of solving mechanics problems involving velocity and position?

Solving mechanics problems involving velocity and position is important because it allows us to understand the motion of objects and predict their future behavior. This is crucial in many fields such as engineering, physics, and astronomy.

What are some common challenges in solving mechanics problems involving velocity and position?

One common challenge is understanding and applying the correct equations of motion. Another challenge is dealing with non-constant acceleration, which requires more advanced mathematical techniques. Additionally, incorrect assumptions or data can also lead to incorrect solutions.

How can I improve my problem-solving skills in mechanics?

To improve your problem-solving skills in mechanics, it is important to practice and familiarize yourself with the equations of motion and their applications. You can also work on developing your mathematical skills and critical thinking abilities. Seeking help from a mentor or tutor can also be beneficial in improving your skills.
