You pull on a wagon resting on the sidewalk. What will happen next?
The wagon moves because you apply more force to the wagon than it applies to you.
The wagon doesn’t move because the force you apply to the wagon is equal to the force it applies to you:
The wagon moves because you apply more friction to the ground.
The wagon doesn’t move because the wagon applies more force to you than you apply to the wagon.
A glass coffee table is able to apply a maximum normal force of 500 N. The floor that it stands on is able to apply a maximum normal force of 65,000 N. A large object with a mass of 50 kg is lowered into the table using a pulley system. What happens if anything to the table?
Nothing will happen to the table, but it will back with a force equal to its weight.
The table will break, and the object will come to rest on the floor:
The table will move.
The table will not be in equilibrium.
Please help! I have no idea what the answers could be...
In the wagon problem I have to say none of the above although the second choice is possible
The third law says the force you exert on the wagon is equal and opposite to the force the wagon exerts on you. Indeed if the maximum friction force is greater than that force the wagon will not move. However the wording does not say that.
-------------------------------------------------------------
50*g = 50 kg * 9.81 = 490.5 Newtons weight
the table holds, barely, first answer, pushes back up with 490.5 N

For the first question, when you pull on a wagon resting on the sidewalk, the most accurate answer would be: "The wagon moves because you apply more force to the wagon than it applies to you." When you exert force on the wagon, it experiences an equal and opposite reaction, causing it to move.
For the second question, based on the information provided, the most accurate answer is: "The table will break, and the object will come to rest on the floor." The maximum normal force the glass coffee table can apply is 500 N, but the mass of the object being lowered is 50 kg, which corresponds to a weight of roughly 490 N (mass x gravitational acceleration). Since the weight of the object is greater than the maximum normal force the table can handle, it will likely break, causing the object to fall and come to rest on the floor.
I hope that helps! Let me know if you have any other questions.
For the first question:
When you pull on a wagon resting on the sidewalk, what will happen next? The correct answer is:
The wagon moves because you apply more force to the wagon than it applies to you.
Explanation: In order for the wagon to move, there needs to be an unbalanced force acting on it. When you apply a force to the wagon by pulling it, the force you apply is greater than the force of friction between the wagon and the ground. This causes the wagon to move.
For the second question:
What happens to the glass coffee table when a large object is lowered onto it?
The correct answer is:
The table will break, and the object will come to rest on the floor.
Explanation: The maximum normal force that the glass coffee table can apply is 500 N, while the floor can apply a maximum normal force of 65,000 N. When a large object with a mass of 50 kg is lowered onto the table, its weight (mass x gravity) exerts a force of 50 kg x 9.8 m/s^2 = 490 N. Since this force exceeds the maximum normal force the table can apply, the table will break and the object will come to rest on the floor.
It's important to note that these answers are based on the given information and assumptions about the scenario.
