A heavy steel cable attached to a motor is lifting a girder. The girder is speeding up.(a) Draw an interaction diagram

Problems 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, and 52 describe a situation. For each, draw a motion diagram, a force-identification diagram, and a free-body diagram.A Styrofoam ball has just been shot straight up. Air resistance is not negligible.

Newton's First Law Exercises 17, 18, and 19 show two of the three forces acting on an object in equilibrium. Redraw the diagram, showing all three forces. Label the third force F3.

Block A in FIGURE EX7.4 is sliding down the incline. The rope is massless, and the massless pulley turns on frictionless bearings, but the surface is not frictionless. The rope and the pulley are among the interacting objects, but you'll have to decide if they're part of the system. (a) Draw an interaction diagram

The rope and the pulley are among the interacting objects, but you'll have to decide if they're part of the system. (c) Draw a free-body diagram for each object in the system. Use dashed lines to connect members of an action/reaction pair.
