SUMMARY

The discussion centers on determining the acceleration of the center of mass of a horizontally moving bar supported at an angle "alfa" with the ground. The bar is assumed to be homogeneous and has a length L. The key to solving the problem lies in expressing the coordinates of the center of mass in relation to the horizontal contact point's movement and the angle with the wall. Participants emphasize the importance of breaking down the problem into smaller steps and ensuring accurate calculations and unit usage.

PREREQUISITES
  • Understanding of basic physics concepts, particularly dynamics and motion.
  • Familiarity with coordinate systems and how to express positions in terms of angles.
  • Knowledge of kinematics equations related to acceleration and velocity.
  • Ability to perform calculations with trigonometric functions relevant to angles.
NEXT STEPS
  • Study the equations of motion for objects at angles, focusing on how to derive acceleration from position coordinates.
  • Learn about the role of trigonometry in resolving forces and accelerations in inclined planes.
  • Explore the concept of center of mass and how it applies to rigid body dynamics.
  • Investigate examples of similar physics problems involving inclined surfaces and horizontal motion.
USEFUL FOR

This discussion is beneficial for physics students, educators, and anyone interested in understanding dynamics involving inclined objects and their motion. It is particularly useful for those tackling similar problems in mechanics.

I found this problem that is theorically simple but I can't reach the result in a satisfatory way, can anyone help me?
It is like this, an object like a bar is suported in a wall with a certain angle "alfa" with the ground and them the contact point in the ground start to move horizontally with a constant velocity. You have to find the aceleration of it's certer of mass in function of the angle. (consider the bar homogeneous and everything else, the contact point with the wall and the ground still in contact during all the problem)
That is it.
Thank you.

Assume the bar has a length L. You should be able to write an expression for the coordinates of the center of mass in terms of the coordinate of the ground contact point. And that contact point coordinate can be expressed in terms of the angle that the bar makes with the wall.
 
, it sounds like you are having trouble solving a physics problem involving an object supported at an angle and moving horizontally with a constant velocity. It can be frustrating when a problem seems simple in theory, but you're having trouble reaching a satisfactory result. I'm happy to try and assist you with this problem. Can you provide more specific information about the problem, such as the specific values for the angle and the velocity, and any other relevant details? That will help me provide a more accurate and helpful response. In the meantime, have you tried breaking the problem down into smaller steps and using equations that relate to the motion of objects at an angle? I would also suggest checking your calculations and making sure you are using the correct units. Let's work together to find a solution to this problem.
