Finding static force and kinetic force

Click For Summary
SUMMARY

The discussion focuses on calculating the coefficient of kinetic friction for a 4.00 kg block pushed along a ceiling with an applied force of 85 N at a 55-degree angle. Given the block's acceleration of 6.00 m/s², participants emphasize the importance of drawing a free body diagram and resolving forces into horizontal and vertical components. The fundamental equation to apply is F = ma, which must be utilized in both directions to solve for the coefficient of kinetic friction.

PREREQUISITES
  • Understanding of Newton's Second Law (F = ma)
  • Knowledge of free body diagrams
  • Ability to resolve forces into components
  • Familiarity with the concept of friction coefficients
NEXT STEPS
  • Study how to draw and analyze free body diagrams
  • Learn about resolving forces into horizontal and vertical components
  • Research the calculation of friction coefficients in physics
  • Explore applications of Newton's Second Law in various scenarios
USEFUL FOR

Students in physics courses, particularly those struggling with mechanics, as well as educators seeking to reinforce concepts of force analysis and friction in practical applications.

Homework Statement


A 4.00 kg block is pushed along the ceiling with aconstant applied force of 85 N that acts at an angle of 55 degrees with the horizontal. The block accelerates to the right at 6.00 m/s2. Determine the coefficient of kinetic force between the block and cieling


Homework Equations


No idea!


The Attempt at a Solution


Again, no idea

Our physics class has been without a degreed teacher since the beginning of the school year and there are serious holes in our classes learning yet we are expected to be learning at the pace of other classes, while this is hardly an excuse I could use some help on this problem.

draw a free body diagram.
split all forces in horizontal and vertical components, you have F = ma in both directions.
