SUMMARY

The discussion focuses on calculating the forces exerted by a 7.0 kg block in a system of three blocks (1.0 kg, 7.0 kg, and 9.0 kg) on a frictionless table, pushed by a 20 N force applied to the 1.0 kg block. The key equations involved are Newton's second law, F=ma, and the concept of force transmission through connected objects. The force exerted by the 7.0 kg block on the 9.0 kg block is determined to be 14 N, while the force it exerts on the 1.0 kg block is 6 N. Understanding free body diagrams (FBD) is essential for visualizing the forces acting on each block.

PREREQUISITES
  • Newton's Second Law (F=ma)
  • Free Body Diagrams (FBD)
  • Basic understanding of mass and force
  • Concept of frictionless surfaces
NEXT STEPS
  • Study how to draw and interpret Free Body Diagrams (FBD)
  • Learn about force transmission in connected systems
  • Explore examples of Newton's laws in multi-body problems
  • Review concepts of frictionless motion and its implications
USEFUL FOR

Students studying physics, particularly those focusing on mechanics, as well as educators seeking to explain force interactions in multi-body systems.

Homework Statement



Blocks with masses of 1.0 kg, 7.0 kg, and 9.0 kg are lined up in a row on a frictionless table. All three are pushed forward by a 20 N force applied to the 1.0 kg block.

A) How much force does the 7.0 kg block exert on the 9.0 kg block?

B) How much force does the 7.0 kg block exert on the 1.0 kg block?I am unsure of where to start or an equation to even use. help on how to solve it would be greatly appreciated

for most of the mechanics problems draw the FBD(labeling all forces) and put in equations obeying F=ma...and solve.

PS: try posting atleast your idea of the problem..
