## Newton's Laws of Motion

1. The problem statement, all variables and given/known data

Two blocks m1 = 8.5 kg and m2 = 4.0 kg are connected by a homogeneous rope that has a mass of mr = 1.14 kg. A constant vertical force, F = 180.4 N, is applied to the upper block. What is the magnitude of the acceleration of the system?

2. Relevant equations

F=ma

3. The attempt at a solution

 Mentor Is gravity involved, or is this the only force acting on the system? What is the total mass of the system?
 Yes gravity is a factor
