Question

You get called to help your friend move. You are asked to move this 125 kg box from the front door into the moving truck, which has a ramp attached to it. You could not move the box at all, even when you pushed your hardest.

Option 1: You should increase the force you apply.
Option 2: You should decrease the force you apply.
Option 3: You should use the ramp to reduce the force needed.
Option 4: You should ask for additional help to move the box.

Answer 1

The correct option is Option 3: You should use the ramp to reduce the force needed. When you use a ramp, it allows you to apply a smaller force over a longer distance, which reduces the amount of force needed to move the box.

Step-by-step explanation:

The correct option is Option 3: You should use the ramp to reduce the force needed.

When you use a ramp, it allows you to apply a smaller force over a longer distance, which reduces the amount of force needed to move the box. The ramp helps to decrease the force required because it allows you to trade off force for distance. By exerting a smaller force over a longer distance, you can still move the box with less effort.

For example, if you were to push the box directly up a vertical surface, you would need to exert a much larger force to overcome gravity and friction. However, using a ramp allows you to distribute the force required over a longer distance, reducing the overall force needed to move the box.
