Question

2 8. [Ipt] A force of magnitude F = 9.30 N pushes three boxes with masses m1 = 1.50 kg, m2 = 2.40 kg, and m3 = 4.90 kg, on a level surface, as shown in the diagram. Draw a free body diagram (FBD) showing all of 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. E.g., if the first force is in direction A, and the remaining forces are not applied to the system, enter i. box 3 pushing on box 2 ii, box 2 pushing on box 1 iii. floor pushing on box 1 iv. floor pushing on box 2 v. box 2 pushing on ground Amsw Submit All AnswersLast Answer: NDNAC

Answer 1

The system of required FBD contains box 2 and 3 together therefore their normal forces pushing each other will not be considered.

hence

for part -1

box 3 pushing on box 2 is not applicable = N

part -2

box 2 will push back box 1 according to the newtons third law therefore it's direction is towards = D

Part-3

Floor will push box 1 in upward direction (Normal force) = A

Part-4

floor will also push box 2 in upward direction = A

part-5

box 2 will push gound in downward direction = C

Therefore the final answer will be in the order mention below
