1. The problem statement, all variables and given/known data A 1.0 kg box on a horizontal frictionless surface is accelerated by attaching a 1.5 kg mass as shown in the diagram. What is the magnitude of acceleration of the box?(Remember, both boxes accelerate.) 2. Relevant equations F = ma 3. The attempt at a solution I drew a free body diagram of all the forces on the system. The only thing I can calculate from here is the force of gravity on the 1.5 kg object. Fg = mg Fg = (1.5 kg) (-9.81m/s^2) Fg = -14.7 N Where do I go from here?
