_____ m/s^2Okay the formula is F(net) = ma

What I did was 31.8/3.41 but it was wrong and I don't know what is wrong and why it is

In summary: The clarinetist grabs his 3.41-kg clarinet case from the top of the piano and holds it in the air with an upward force of 31.8 N. The resulting net force is -1.62 N, which causes the clarinet to experience a downward acceleration of -0.79 m/s^2.

OK, and what is Fnet? You have two forces acting on the clarinet.

Wouldn't it just be the 31.8N

It is the vector sum of ALL the forces acting on the body.

In this case you have TWO forces, as it was pointed out already.

One is the force of the hand, upward. The other one is the weight of the clarinet, downwards.

What is the magnitude of this second one?

And then what is the magnitude of the net force? Don't forget that the two forces are in opposite directions.

There are two forces acting on the clarinet: weight and force FROM the hand.

The net force ON THE CLARINET is only due to the force acting ON THE CLARINET. The two mentioned above. Forces on other objects, like hands, pianos, etc do not matter when we calculate net force on the clarinet.

So let's try one more time.

We have, on the clarinet, the force of 31.8 N upwards and the weight of the clarinet (calculate it) downwards. What is the resultant or net force?

28.39 kg?

You cannot subtract a mass from a force. Does not make sense.

You need to find the WEIGHT of the clarinet. You are given the mass, 3.41 kg.

Do you know how to find the weight, in N?

W=mg which in my case is (3.41kg * 9.8 m/s^2) which is 33.42N?

Yeah, so you have 31.8 N up, and 33.42 N down, so what is the net force?

Newton's second law clarinet problem is a physics problem that involves the application of Newton's second law of motion to the motion of a clarinet reed. It is used to explain the mechanism behind the production of sound in a clarinet.

Newton's second law of motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. In other words, the greater the force applied to an object, the greater its acceleration will be, and the more massive an object is, the less it will accelerate for a given force.

In the clarinet, when air is blown through the mouthpiece, it exerts a force on the reed. According to Newton's second law, this force causes the reed to accelerate, causing it to vibrate. The vibrations of the reed then produce the sound waves that create the sound of the clarinet.

The variables involved in this problem include the mass of the reed, the force applied by the air, the acceleration of the reed, and the resulting sound waves. Other factors such as the length and shape of the clarinet may also affect the sound produced.

The application of Newton's second law to the clarinet reed can be used as a model for understanding sound production in other wind instruments. By understanding how the force of air causes the reed to vibrate and produce sound, we can apply this concept to other instruments such as the saxophone, flute, or oboe.
