Question

A boy is pushing a chair by applying a force of 5 newtons. His mother helps him push it faster by applying an additional force of 7 newtons in the same direction. What is the net force acting on the chair? A. 2 newtons B. 5 newtons C. 7 newtons D. 12 newtons E. 14 newtons

Answer 1

The net force acting on the chair is D. 12 newtons.

Step-by-step explanation:

The net force acting on the chair can be calculated by adding the individual forces applied by the boy and his mother. The boy applies a force of 5 newtons in the same direction as the motion, and his mother applies an additional force of 7 newtons. To determine the net force, we add these two forces together:

Net force = 5 N + 7 N = 12 N

Therefore, the net force acting on the chair is 12 newtons (D).
