Newtons laws on car fuzzy dice

In summary, the conversation discusses finding the acceleration of a car based on the angle of a fuzzy dice hanging from the rear view mirror. The equations F=ma and Fr=mac are mentioned, and the speaker is unsure of where to start. They suggest drawing a Free Body Diagram, and describe the vectors of force of gravity, tension, and normal force in relation to the dice.

Homework Statement


You have a fuzzy dice with mass .2kg hanging from the rear view mirror. When you step on the gas the dice makes an angle of 25 degrees. what is car's acceleration?


Homework Equations


F=ma...?
Fr=mac..?


The Attempt at a Solution


Im really not sure where to start. I would need first find force, correct?

The first thing to do is ...

Draw a Free Body Diagram.

ok :) so I have Force of W(Gravity) Pointing down on neg x-axis and i have a Tension vector pointing out in the 3rd quadrant making a 25 degree angle and finally the Normal force vector pointing up. Is that right?

1. What are Newton's laws of motion?

Newton's laws of motion are three fundamental principles that describe the behavior of objects in motion. They are:

  • First law: An object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity, unless acted upon by an external force.
  • Second law: The force applied to an object is equal to its mass multiplied by its acceleration.
  • Third law: For every action, there is an equal and opposite reaction.

2. How do Newton's laws apply to a car?

Newton's laws apply to a car in the same way as they apply to any other object. The car will remain at rest or continue moving at a constant speed unless acted upon by an external force, such as the engine or brakes. The force applied by the engine is equal to the car's mass multiplied by its acceleration, and the car will experience an equal and opposite reaction from the ground as it moves forward.

3. What is the role of fuzzy dice in Newton's laws?

Fuzzy dice do not play a direct role in Newton's laws. However, they can be used as a visual aid to demonstrate the effects of Newton's laws on a moving object, such as a car. For example, if a car with fuzzy dice hanging from the rearview mirror suddenly accelerates, the fuzzy dice will appear to move backwards due to the inertia of the objects inside the car.

4. How do Newton's laws affect a car's movement?

Newton's laws dictate how a car will move based on the forces acting upon it. The first law explains why a car will stay at rest or continue moving at a constant speed, the second law explains how the car will accelerate or decelerate, and the third law explains the equal and opposite forces involved in the car's movement.

5. Are Newton's laws still relevant in modern cars?

Yes, Newton's laws are still relevant in modern cars. The laws of motion have not changed, and they still apply to all objects, including cars. In fact, engineers use Newton's laws to design and improve cars for better performance and safety.
