Object A is connected to object B via a string of negligible mass that passes over a pulley (also of negligible mass). Object A is placed on a level surface that does have some amount of friction associated with it. Both objects are at rest initially. Once released, object A will accelerate to the left, and objective B will accelerate downwards. Please choose a coordinate system for which the direction of acceleration is positive. 1. Draw and label a force diagram for objective A and B and a force diagram describing the tug of war acting on objective A and B being treated together as the system. 2. In each case, write summation statements without solving for anything in particular.
