Question

Part A.)Six boxes held at rest against identical walls.
Rank the boxes on the basis of the magnitude of the normal forceacting on them.
Rank from largest to smallest. To rank items as equivalent, overlapthem.

1.)130N--->7kg

2.)150N--->1kg

3.)150N--->7kg

4.)120N--->3kg

5.)140N--->5kg

6.)140N--->3kg

(Since the boxes are at rest, Newton's 2nd law dictates thatthe horizontal forces on each box must add up to zero. You can usethis information to determine the normal forces. If two boxes areboth pushed against the wall by the same force, then they shouldexperience the same normal force.)

Part B.) Rank the boxes on the basis of thefrictional force acting on them.

Rank from largest to smallest. Torank items as equivalent, overlap them.

1.)130N--->7kg

2.)150N--->1kg

3.)150N--->7kg

4.)120N--->3kg

5.)140N--->5kg

6.)140N--->3kg
