Question

1. A worker pushes horizontally on a 2000 N refrigerator on a kitchen floor with a force of 25 N. Which statement is the most accurate about the situation?

A. If the refrigerator moves forward, this person feels it pushing back with less than 25 N.
B. The person feels a 25 N push from the refrigerator only if it does not move.
C. The person always feels a 25 N push from the refrigerator.
D. The person feels a 2000 N push from the refrigerator.

Help Please.

Answer 1

If the refrigerator moves forward, this person feels it pushing back with less than 25 N. (while it is accelerating). If it is in constant speed, the refigerator is exactly pushing back with 25N.

Answer 2

To determine the most accurate statement about the situation, we need to consider Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. In this case, the worker is pushing on the refrigerator with a force of 25 N.

A. If the refrigerator moves forward, this person feels it pushing back with less than 25 N.
This statement is inaccurate because according to Newton's third law, the reaction force exerted by the refrigerator on the person would be equal in magnitude to their applied force, which is 25 N.

B. The person feels a 25 N push from the refrigerator only if it does not move.
This statement is also inaccurate because even if the refrigerator is moving, the person would still feel the push exerted by the refrigerator, again, according to Newton's third law.

C. The person always feels a 25 N push from the refrigerator.
This statement is accurate. According to Newton's third law, the person will always feel a push from the refrigerator with the same magnitude as the force they apply on it, which in this case is 25 N.

D. The person feels a 2000 N push from the refrigerator.
This statement is inaccurate because the person is only applying a force of 25 N on the refrigerator, so they will not feel a push of 2000 N.

Therefore, the most accurate statement about the situation is C. The person always feels a 25 N push from the refrigerator.

Answer 3

1. A worker pushes horizontally on a 2000 N refrigerator on a kitchen floor with a force of 25 N. Which statement is the most accurate about the situation?

I think C

If the refrigerator moves forward, this person feels it pushing back with less than 25 N. (while it is accelerating). If it is in constant speed, the refigerator is exactly pushing back with 25N.

To determine the most accurate statement about the situation, we need to consider Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. In this case, the worker is pushing on the refrigerator with a force of 25 N.

So A? Thank you so much.
