Question

calculating net forces
interpret each drawing of forces on the box. calculate and write the resulting net force
on the blank below the box (make sure to include the correct unit of measure). on the
next blank, write the word balanced or unbalanced and circle the arrow for the direction
of the resulting net force.

1. 2.
2. 4.
3. 6.
4. 8.

Explanation:

Step1: Determine the direction of forces

Forces to the right are positive, forces to the left are negative.

Step2: Calculate net force for each case

1. \(F_{net}=100-(50 + 75)=100 - 125=- 25N\) (unbalanced, left)
2. \(F_{net}=(545 + 732)-(732+545)=0N\) (balanced)
3. \(F_{net}=(61 + 192)-61=192N\) (unbalanced, right)
4. \(F_{net}=(1231+562)-(489 + 956)=1793-1445 = 348N\) (unbalanced, right)
5. \(F_{net}=(653+352)-1000=1005 - 1000=5N\) (unbalanced, right)
6. \(F_{net}=8732-0 = 8732N\) (unbalanced, right)
7. \(F_{net}=577-2957=-2380N\) (unbalanced, left)
8. \(F_{net}=83 - 96=-13N\) (unbalanced, left)

Answer:

1. \(-25N\), unbalanced (left)
2. \(0N\), balanced
3. \(192N\), unbalanced (right)
4. \(348N\), unbalanced (right)
5. \(5N\), unbalanced (right)
6. \(8732N\), unbalanced (right)
7. \(-2380N\), unbalanced (left)
8. \(-13N\), unbalanced (left)
