SUMMARY

This discussion focuses on verifying work relations in a physics problem involving two blocks with masses m1 = 2.40 kg and m2 = 1.80 kg. The relevant work relations are defined as Wtotal = ΔK, Wc = -ΔU, and Wnc = ΔE. The user has calculated the distance d = 0.937 m, Wc = 16.5 J, and Wnc = -7.72 J, but seeks clarification on the interpretation of these results and the need for a diagram to visualize the problem.

PREREQUISITES
  • Understanding of classical mechanics principles
  • Familiarity with work-energy theorem
  • Knowledge of kinetic and potential energy equations
  • Ability to interpret and create free-body diagrams
NEXT STEPS
  • Review the work-energy theorem in classical mechanics
  • Study the concepts of kinetic energy (KE) and potential energy (PE)
  • Learn how to derive and interpret free-body diagrams
  • Explore problem-solving techniques for systems of connected masses
USEFUL FOR

Students studying physics, educators teaching mechanics, and anyone involved in solving work-energy problems in classical mechanics.

I need to verify these three work relations and don't know where to even start.

Wtotal= ΔK, Wc= -ΔU and Wnc = ΔE


The details for the whole problem were A block of mass m1 = 2.40 kg is connected to a second block of mass m2 = 1.80 kg, as shown in the figure. The two masses start from rest and are moving with a speed of 2.05 m/s just before m2 hits the floor.

I already figured out the answers to the first three parts of the questions and the answers were.

d=0.937m
Wc=16.5J
Wnc=-7.72J

Honestly I'm not sure what they are even looking for as means for an answer.

It would help if you could give us a diagram.

I apologize, I knew I forgot something.
