120N
N8'0
ON

Answers

Answer 1

Answer:

120N

Explanation:

Newton's second law formula: F= ma

given that m = 10 kg, a = 12 m/s^2

F = ma = 10 kg * 12 m/s^2 = 120 kgm/s^2 = 120 N

Answer 2

The force acting on the box is equal to 120N. Therefore, option (A) is correct.

What is Newton's second law of motion?

According to Newton's 2nd law of motion, The force acting on an object is equal to mass times the acceleration of that object.

This law tells that the acceleration of a moving body depends upon two variables in which one is the mass of the object which is constant while the other is the force acting on that object. The acceleration of an object increases as the mass of the object is less.

The mathematical equation of the second law of motion can be written as:

F = ma

Given, the mass of the box, m = 10 Kg

The acceleration of the box, a = 12m/s²

We can find the force acting on the box by putting the values a and m:

Force acting on the box, F = 10 ×12 = 120 N

Therefore, the force acting on the box is equal to 120 newtons.

9. How is spring potential energy determined from a force versus position graph?

Answers

Answer: The potential energy associated with a mass attached to a spring depends on how much the spring is stretched or compressed. ... The gravitational force on the mass is −mg (“−” because the force points down). The force is the negative of the slope on the potential energy versus position graph.

Explanation:

:)

By getting the data from the graph of force versus displacement we can calculate the Potential energy of the spring.

What will be the potential energy?

As we know that potential energy is defined as the energy possessed by the body due to its position with respect to other positions.

For an example the potential energy of an object if it is placed at height h will be due to the gravitational acceleration of the earth and is given by  [tex]PE=mgh[/tex]

Similarly, for a spring-mass system, the potential energy will be due to the weight of the mass that will be the force exerted by the mass on the spring so there will be an extension in the spring.

So this extension will be found out by the force and displacement  graph as the position of the mass attached to the spring goes down so the potential energy can be calculated as the

[tex]PE= F\times X[/tex]

[tex]F=mg[/tex]  weight of the mass

X= deflection of the spring

Thus by getting the data from the graph of force versus displacement we can calculate the Potential energy of the spring.
