Two Dogs and a Tire: A Physics Experiment

In summary, two dogs, separated by a 137 degree arc, were pulling a tire simultaneously. The first dog exerted a force of 220N while the second dog exerted a force of 230N. A third dog joined in and pulled with enough force to bring all three dogs and the tire to a standstill. The third dog was located in relation to the pit bull and was pulling with the resultant force of two forces at an angle of 137 degrees.

1. Two dogs, separate by 137 degree of arc, grab a tire and pull simultaneously. The first dog pulls with a force of 220N. The second dog pulls with a force of 230N. A third dog joins in on the fun and grabs the tire as well, pulling just enough to bring thee other 2 dogs and the tire to a standstill.

1. Relative to the pit bull, where is the 3rd dog?

2. With how much force is the 3rd dog pulling the tire?




2. F=MA



3. http://i36.tinypic.com/2z6tumw.jpg

Not sure to be honest

Nevermind, got it.

Find the resultant of two forces 220 N and 230 N with an angle 137 degree with each other. That will be the pulling force of the third dog.
 

1. How does the tire's weight affect the experiment?

The tire's weight affects the experiment in several ways. First, the weight of the tire will determine how much force is needed to move it. This force must be greater than the weight of the tire in order for it to roll. Additionally, the weight of the tire will affect the distance it travels after being released. The heavier the tire, the more momentum it will have and the farther it will roll.

2. Can the experiment be done with any type of tire?

Yes, this experiment can be done with any type of tire. However, the type of tire used may affect the results. For example, a wider tire may have more surface area in contact with the ground, resulting in more friction and a shorter distance traveled. On the other hand, a narrower tire may have less surface area and less friction, resulting in a longer distance traveled.

3. How does the surface on which the experiment is conducted affect the results?

The surface on which the experiment is conducted can greatly affect the results. A smooth, flat surface will result in less friction and a longer distance traveled by the tire. However, a rough or uneven surface will increase friction and may cause the tire to stop rolling sooner. It is important to keep the surface consistent for accurate results.

4. What other factors besides weight can affect the distance the tire travels?

In addition to weight, other factors that can affect the distance the tire travels include the angle at which it is released, the force used to push it, and the shape and condition of the tire. The angle and force will determine the initial velocity of the tire, while the shape and condition of the tire can affect its rolling resistance and momentum.

5. How does this experiment relate to physics?

This experiment relates to physics in several ways. First, it demonstrates the concept of force and how it can affect motion. It also illustrates Newton's laws of motion, specifically the law of inertia and the law of action and reaction. Additionally, the experiment involves measuring distance and time, and calculating velocity and momentum, all of which are fundamental concepts in physics.
