Part B In most problems, after you have drawn the free-body diagrams, you will explicitly label your coordinate axes and directions. Always make the object of interest the Identify the forces acting on the object of interest. From the list below, select the forces that act on the piano. origin of your coordinate system. Then you will need to divide the forces into x and y components, sum the x Check all that apply. and y forces, and apply Newton's first or second law. In this problem you will only draw the free-body O acceleration of the piano diagram. gravitational force acting on the piano (piano's weight) Figure J speed of the piano gravitational force acting on Chadwick (Chadwick's weight) force of the floor on the piano (normal force) O force of the piano on the floor force of Chadwick on the piano a O force of the piano pushing on Chadwick Submit Request
