SUMMARY

The discussion focuses on calculating the forces required to move and accelerate a trunk weighing 220 N, with a static friction coefficient of 0.41 and a kinetic friction coefficient of 0.32. The minimum horizontal force needed to initiate movement is determined by the static friction force, which is 90.2 N. To maintain constant velocity, a horizontal force equal to the kinetic friction force of 70.4 N is required. If the initial force used to start the motion is continuously applied, the trunk will experience an acceleration of 0.09 m/s².

PREREQUISITES
  • Understanding of Newton's laws of motion
  • Knowledge of static and kinetic friction coefficients
  • Basic algebra for force calculations
  • Familiarity with the concept of acceleration
NEXT STEPS
  • Study the application of Newton's second law in real-world scenarios
  • Learn about the differences between static and kinetic friction in detail
  • Explore the calculation of acceleration using net force and mass
  • Investigate frictional force calculations in various materials and surfaces
USEFUL FOR

Physics students, mechanical engineers, and anyone interested in understanding the dynamics of forces and motion in practical applications.

Weight of the trunk = 220 N (rests on the floor)
Static friction between the trunk and floor = 0.41
Kinetic friction = 0.32

I want to find the minimum magnitude for horizontal force while I'm starting to push on the trunk. Secondly, what magnitude of the horizontal force must be apply in order to keep the trunk in constant velocity and last but not least, if i continuously to push with the force used to start the motion, what would be the acceleration of the trunk?

Help me on this problem..:shy:

Welcome to PF.

So start with what is the force of static friction?
What is the force of kinetic friction?
