A 2.285 kg object is held in place on an inclined plane that makes an angle of 40 degrees with the horizontal. The coefficient of static friction between the plan and the object is 0.552. A second object that has a mass of 4.75 kg is connected to the first object with a masless string over a massless, frictionless pulley. Calculate the inital acceleration of the system and tension in the string once the objects are released.
