Solving the Forces on a Frictionless System

Click For Summary
SUMMARY

The discussion focuses on solving a physics problem involving three blocks (M1 = 1.10 kg, M2 = 2.40 kg, M3 = 3.60 kg) connected by massless strings on a frictionless surface. The problem requires calculating the tension T2 in the system, given that T1 is 2.10 N and a force F is acting on M3. Participants emphasize the importance of labeling all forces and applying the net force equation to derive the solution effectively.

Homework Statement



Three blocks on a frictionless surface are connected by massless strings, with M1 = 1.10 kg, M2 = 2.40 kg, and M3 = 3.60 kg. Due to the force F acting on M3, as shown, the system accelerates to the right. Given that T1 is 2.10 N, calculate T2

Label all the forces acting on all three of the blocks. Then do the usual net force equation. See where this gets you.
 
Yep, that makes sense and I got it right. Thanks for your help.
