(8%) Problem 6: A first object, with mass M1, is placed on a wooden surface. It is connected with an ideal, meaning massless and inelastic, string that passes over an ideal, meaning massless and frictionless, pulley. A second object, with mass M2, hangs from the other end of the string. The system is released from rest, and the objects accelerate.

Using a rope attached to the heavy box, an individual applies a force which is insufficient to move it. F Otheexpertta.com A From the options listed, check all of the forces that should appear on the free body diagram of the heavy box. Grade Summary The normal force of the floor acting on the heavy box. Deductions % The force on the heavy box applied through the tension in the rope. Potential 100% An inelastic or spring force applied to the heavy box. Submissions O The force of kinetic friction acting on the shoes of the person. Attempts remaining: 5 The weight of the heavy box.
