Forces in Two Dimensions: Net Force and Components

In summary, the problem involves a 1.00 kg body with an acceleration of 9.01 m/s2 at an angle of 39° to the positive x axis. The x and y components of the net force and the net force in unit-vector notation are needed to be determined. The formula F=ma is typically used in forces problems, but a diagram may also be helpful in visualizing the situation. It is important to put in effort and show some understanding of the problem in order to receive assistance.

Homework Statement


If a 1.00 kg body has an acceleration of 9.01 m/s2 at 39° to the positive direction of the x axis, then what are (a) the x component and (b) the y component of the net force on it, and (c) what is the net force in unit-vector notation?

Homework Equations


F=ma?

The Attempt at a Solution



I literally have no idea what to do. Rather than just putting the answer, can you explain in detail as to why you would do "this" in a forces problem like this, and what formulas are usually used in forces (aside from f=ma)

can you at least draw a diagram of what's going on? Without SOME effort on your part, this thread will be closed or deleted.
 

Related to Forces in Two Dimensions: Net Force and Components

1. What are forces and how do they affect objects?

Forces are interactions between two objects that cause a change in motion. They can be classified as either contact forces, such as pushing or pulling, or non-contact forces, such as gravity or magnetism. Forces can change the speed, direction, or shape of an object.

2. How can I calculate the net force on an object?

To calculate the net force on an object, you need to determine the individual forces acting on the object and their direction. Then, you can use the formula Fnet = ma, where Fnet is the net force, m is the mass of the object, and a is the acceleration. The net force will be in the same direction as the acceleration.

3. What is the difference between mass and weight?

Mass is a measure of the amount of matter in an object, while weight is a measure of the force of gravity acting on an object. Mass is measured in kilograms (kg), while weight is measured in newtons (N). Mass remains constant regardless of an object's location, but weight can change depending on the strength of gravity.

4. How do forces affect an object's equilibrium?

An object is in equilibrium when the net force acting on it is zero, meaning there is no change in motion. If forces are unbalanced, the object will accelerate in the direction of the greater force. If forces are balanced, the object will remain at rest or continue to move at a constant velocity.

5. Can forces be seen?

Forces themselves cannot be seen, but their effects can be observed. For example, we can see an object being pushed or pulled, or we can see the effects of gravity on objects. Some forces, such as magnetism or friction, may not be visible, but their effects can be observed.
