How large is the resultant force on Gavin's toy car after he kicks it?

In summary, Gavin is kicking a toy car with a force of 2.4 N. The car weighs 1.2 kg and has friction-free wheels, resulting in a small friction force. The question asks about the resultant force, and if there is no friction, it should be pointing forward. However, the book states that the resultant force is zero, which is confusing. The conversation suggests translating the problem into common English/Physics language to better understand the concepts of "crackle" and "power", which are not commonly measured in Newtons.

Homework Statement


Gavin is kicking one of his toy cars with a force straight ahead. the car weighs 1.2 kg and has friction free wheels so that the friction forces of the car is small when it has started. Gavin kicks his car with the force of 2.4 N. How large is the resultant force?

Homework Equations


No equation

The Attempt at a Solution


If there is no friction then the resultant force should be pointing forward but my book is saying that the resultant force is zero. why?

Why don't you translate the problem into common English / Physics language so that all can understand it? Perhaps the verb "to crackle" means something non-obvious in this punk-speak dialect? And power certainly isn't measured in Newtons in any unit system that I'm aware of. So how are we to know what "resultant" or "force" really translate to?

lol I used google translate :P I have updated it now

What is the resultant force on a car?

The resultant force on a car is the overall force acting on the car, taking into account all the individual forces acting upon it. It is the net force that determines the car's motion.

How is the resultant force on a car calculated?

The resultant force on a car is calculated by adding all the individual forces acting on the car in the same direction, and subtracting any forces acting in the opposite direction. This is known as vector addition.

What are some examples of forces acting on a car?

Some examples of forces acting on a car include the engine's driving force, air resistance or drag, and the force of friction between the tires and the road. Other forces can include gravity, wind, and the weight of any objects inside the car.

How does the resultant force affect the motion of a car?

The resultant force on a car determines its acceleration and direction of motion. If the resultant force is zero, the car will maintain a constant speed. If the resultant force is greater than zero, the car will accelerate in the direction of the resultant force. If the resultant force is in the opposite direction of motion, the car will decelerate or slow down.

How can the resultant force on a car be changed?

The resultant force on a car can be changed by altering the individual forces acting on the car. For example, pressing the gas pedal will increase the engine's driving force, resulting in a greater resultant force and acceleration. Changing the direction of the car or adjusting the weight of objects inside the car can also affect the resultant force.
