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.)
F = ma
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?
