Question

balanced/unbalanced forces practice problems
problem\tnet force equation (include direction of force & label)\tbalanced or unbalanced? (circle answer)
50 n right and 100 n left\t100 - 50 = 50n\tbalanced unbalanced
7 n\t10 n\t10 - 7 = 2n left\tbalanced unbalanced
left right\t7n - 7n = 0 n\tbalanced unbalanced
30 n\t45 n\t\tbalanced unbalanced

Explanation:

Step1: Calculate net - force for 30 N and 45 N forces

Net force is the sum of forces acting on an object. Since both forces are in the same direction (right - hand side), we add them. The net force $F_{net}=30 + 45=75$ N to the right.

Step2: Determine if forces are balanced or unbalanced

Balanced forces have a net force of 0 N. Since the net force here is 75 N (not 0 N), the forces are unbalanced.

Answer:

Net Force Equation: $30 + 45=75$ N right
Balanced or Unbalanced: Unbalanced
