What is the acceleration of a block being pulled up a slope by a 140 N force?

Click For Summary
SUMMARY

The discussion focuses on calculating the acceleration of a 10.0 kg block being pulled up a 35-degree slope by a force of 140 N, with a coefficient of friction of 0.100. The key to solving this problem involves understanding the forces acting on the block, including gravitational force, normal force, and frictional force. The user is advised to create a free-body diagram to visualize these forces and apply Newton's second law to determine the block's acceleration.

PREREQUISITES
  • Understanding of Newton's second law of motion
  • Knowledge of free-body diagrams
  • Familiarity with frictional force calculations
  • Basic trigonometry for resolving forces on an incline
NEXT STEPS
  • Learn how to draw and analyze free-body diagrams for inclined planes
  • Study the calculation of frictional forces using the coefficient of friction
  • Explore the application of Newton's second law in multi-force scenarios
  • Investigate the effects of different angles of incline on acceleration
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and dynamics, as well as educators looking for examples of force analysis on inclined planes.

Ff=UN



The Attempt at a Solution



I am having trouble getting started and putting the parts of the problem together.
 
Physics news on Phys.org
Start with a picture and free-body diagram.

I have a free body which a 140 N force going along the + x-axis a N force (normal) going + along Y axis a vector "W" in the third quad with a polar angle of 235'. What do i do next. I know that i need to find the acceleration of the block. Where and how does the coeficient of friction come into play here?
 
I still need that picture with all forces shown. There is gravity and friction in addition to that 140 N force. The resultant force accelerates the block.
