Mr. Licht starts pulling a wagon (mass = 25.0 kg) from rest along a horizontal sidewalk. The sidewalk provides a frictional force of 75 N on the wagon. A. If Mr. Licht pulls on the handle with a horizontal force 85 N, what will be the speed of the wagon after 4.0 s? (Draw a free body diagram of the forces acting on the wagon.) B. C. After pulling the wagon for 4.0 s, Mr. Licht changes the force on the handle and pulls horizontally with a force of 75 N. What is the speed of the wagon after another 3.0 s? Using Newton's laws of motion, describe the dynamics of the wagon for: part A Mr. Licht starts pulling a wagon (mass = 25.0 kg) from rest along a horizontal sidewalk.
