SUMMARY

The discussion revolves around solving a physics problem involving two blocks, M1 and M2, connected by a string over a frictionless pulley. The key objective is to determine the minimum coefficient of kinetic friction (µk) that prevents the blocks from moving, as well as the acceleration of M1 and the tension in the string. The problem specifies that the coefficient of kinetic friction is less than the coefficient of static friction, and gravity (g) is the only known constant. Participants emphasize the need to establish relationships between the forces acting on the blocks to derive the necessary equations.

PREREQUISITES
  • Understanding of Newton's laws of motion
  • Knowledge of friction coefficients (static and kinetic)
  • Familiarity with basic pulley systems and tension in strings
  • Ability to manipulate algebraic equations to solve for unknowns
NEXT STEPS
  • Study the concepts of static and kinetic friction in detail
  • Learn how to apply Newton's second law to systems involving pulleys
  • Explore the derivation of equations for tension and acceleration in connected mass systems
  • Practice solving similar physics problems involving friction and motion
USEFUL FOR

Students studying physics, particularly those preparing for AP exams, educators teaching mechanics, and anyone looking to enhance their problem-solving skills in dynamics and friction scenarios.

Ok this is my AP Homework just one question

The block of mass M1 is on a rough horizontal table. The string that attaches it to the block of mass M2 passes over a frictionless pulley of negligible mass. The coefficient of kinetic friction µk between M1 and the table is less than the coefficient of static friction M1

(a) In terms of M1 and M2 determine the minimum value of µk that will prevent the blocks from moving?The blocks are set in motion byy giving M2 a momentary push. In terms of M1,M2,µk and g determine each of the following..

(b)The magnitude of the acceleration of M1?(c) The tension in the string?Okay well i have no idea where to start because there are no given masses only thing known is gravity and nothing more so I am really confused does anyone have any ideas..

K i think this might help but I've figured that friction = tension since nothing is moving or at least that's what i think.

And I don't really need an answer or anything just some help on how to start.
