Question

4. Dani and Gina are pushing on a box. Dani pushes with 250N of force and Gina pushes with 100 N of force. a. What is the net force if they both push in the same direction? b. What is the net force if they both push in the opposite direction?

How great is the air resistance (drag) that acts on a 100cool that

Answer 1

150

Step-by-step explanation:

When Dani and Gina push in the same direction, the net force is the sum of their individual forces. In this case, Dani is pushing with a force of 250N and Gina is pushing with a force of 100N. To find the net force, we simply add these two forces together: 250N + 100N = 350N. Therefore, the net force when they both push in the same direction is 350N.

b. When Dani and Gina push in opposite directions, the net force is the difference between their individual forces. In this case, Dani is pushing with a force of 250N and Gina is pushing with a force of 100N, but in opposite directions. To find the net force, we subtract the smaller force from the larger force: 250N - 100N = 150N. Therefore, the net force when they both push in opposite directions is 150N.

In both cases, it is important to note that the net force determines the overall motion of the box. If the net force is non-zero, the box will accelerate in the direction of the net force. If the net force is zero, the box will remain at rest or continue moving at a constant velocity.
