## Homework Statement

A force of magnitude F= 7.30 N pushes three boxes with masses m1= 1.80kg, m2= 3.00kg and m3= 4.20kg, on a level surface.

Draw a free body diagram showing all the individual forces acting on the system consisting of boxes 2 and 3 together. Indicate the directions of the five forces listed below, choosing from vectors A-D in the diagram. If a force does not belong on the FBD, enter N.

i) gravity pulling on box 3

ii) gravity pulling on box 2

iii) box 1 pushing on box 3

iv) floor pushing on box 2

v)floor pushing on box 1
