An object with mass M1 of 2.85 kg is held in place on an inclined plane that makes an angle 0 of 40.0' with the horizontal (see figure below}. The coefficient of kinetic friction between the plane and the object is m; = 0.552. A second object that has a mass M2 of 4.75 kg is connected to the first object with a massless string over a massless, frictionless pulley. Static friction 1) Calculate the initial acceleration of the system once the objects are released. (Express your answer to three significant figures.) _ Submit Your submissions: 5-32 x Computed value: 5.32 Submitted: Thursday, September 22 at 3:01 PM Feedback
