This discussion focuses on solving a physics problem related to Newton's Second Law, specifically involving two masses, M1 and M2. The key equations referenced are F = ma and F = 0, with emphasis on the need to account for non-zero acceleration. Participants suggest setting up equations using Fnet = ma for both masses to determine the correct acceleration and forces acting on them.
PREREQUISITESStudents studying physics, particularly those tackling dynamics and forces, as well as educators looking for problem-solving strategies in Newtonian mechanics.
The acceleration is not zero here -- the masses do start moving, and you are to find what the acceleration is.jaytm2291 said:Homework Statement

Homework Equations
F = ma
F = 0
That would be true if the acceleration were zero, but it isn't.The Attempt at a Solution
T = Fg for M1
Again, you'd use Fnet=ma to set up two equations for this mass. One equation for motion parallel to the surface, another for the force perpendicular (normal) to the surface.M2 = T - ma = T-M2a
Let's try to set up all the Fnet=ma equations properly, then we'll go from there.I don't know what to do after this.
