Given : Acceleration of the ball is 9.8 m / s² . The pulling force is 1.4 N .

To Find : The mass of the ball .

Solution : It is given that a ball accelerates download with a acceleration of 9.8 m / s² . And the acting force is 1.4 N .

We know that , Force acting is equal to the product of mass and acceleration . That is ,

[tex]\boxed{\purple{\bf Force=mass\times acceleration}}[/tex]

⇒ Force = mass × accelerⁿ

⇒ 1.4 N = mass × 9.8 m / s²

⇒ mass = 1.4 N / 98 m/s²

⇒ mass = 14N / 98 m/s².

⇒ mass = 1/7 kg .

Hence the mass of the object is 1/7 kg ≈ 0.14 kg.

Answer:

a)

a = 2 [m/s^2]

b)

a = 1.6 [m/s^2]

c)

xt = 2100 [m]

Explanation:

In order to solve this problem we must use kinematics equations. But first we must identify what kind of movement is being studied.

a)

When the car moves from rest to 40 [m/s] by 20 [s], it has a uniformly accelerated movement, in this way we can calculate the acceleration by means of the following equation:

[tex]v_{f} = v_{i}+(a*t)[/tex]

where:

Vf = final velocity = 40 [m/s]

Vi = initial velocity = 0 (starting from rest)

a = acceleration [m/s^2]

t = time = 20 [s]

40 = 0 + (a*20)

a = 2 [m/s^2]

The distance can be calculates as follows:

[tex]v_{f} ^{2} = v_{i} ^{2}+(2*a*x)[/tex]

where:

x1 = distance [m]

40^2 = 0 + (2*2*x1)

x1 = 400 [m]

Now the car maintains its speed of 40 [m/s] for 30 seconds, we must calculate the distance x2 by means of the following equation, it is important to emphasize that this movement is at a constant speed.

v = x2/t2

where:

x2 = distance [m]

t2 = 30 [s]

x2 = 40*30

x2 = 1200 [m]

b)

Immediately after a change of speed occurs, such that the previous final speed becomes the initial speed, the new Final speed corresponds to zero, since the car stops completely.

[tex]v_{f} = v_{i}-a*t[/tex]

Note: the negative sign of the equation means that the car is stopping, i.e. slowing down.

0 = 40 - (a *25)

a = 40/25

a = 1.6 [m/s^2]

The distance can be calculates as follows:

[tex]v_{f} ^{2} = v_{i} ^{2} -2*a*x3\\[/tex]

0 = (40^2) - (2*1.6*x3)

x3 = 500 [m]

c)

Now we sum all the distances calculated:

xt = x1 + x2 + x3

xt = 400 + 1200 + 500

xt = 2100 [m]

Answer:

100

Explanation:

The final velocity of the object after the force acts is 2.5 meters per second.

To calculate the final velocity of the object after the force acts, we can use Newton's second law of motion, which states that:

Force = Mass × Acceleration

We need to find the acceleration of the object first. Since the object was initially at rest, its initial velocity (u) is 0 m/s.

The force acting on the object is 500 N, and the mass of the object is 0.20 kg. We can rearrange the equation to find the acceleration (a):

Acceleration (a) = Force / Mass

a = 500 N / 0.20 kg

a = 2500 m/s²

Now, we can use the kinematic equation to find the final velocity (v) of the object:

Final velocity (v) = Initial velocity (u) + (Acceleration × Time)

The initial velocity (u) is 0 m/s (since the object was initially at rest), and the time interval (t) is 0.001 second.

Final velocity (v) = 0 m/s + (2500 m/s² × 0.001 s)

v = 0 m/s + 2.5 m/s

v = 2.5 m/s

Hence, the final velocity of the object after the force acts is 2.5 meters per second.

Answer:

ELECTRONS

Explanation:

The situation in which one particle has a positive charge and one has a negative charge will result in the two particles being attracted to each other.

It states that the force between two charged particles is directly proportional to the product of the magnitude of the charges and inversely proportional to the square of the distance between them.

Given is Coulomb's law which describes how the charge on and distance between two particles affect the electric force between them.

From the properties of charges, we know that the like charges repel and unlike charges attract each other. This means that two positive charges will repel each other and two negative charges will also repel each other. However, if one positive and one negative charge are brought closer to one another, than they will attract each other.

Therefore, the situation in which one particle has a positive charge and one has a negative charge will result in the two particles being attracted to each other.

Answer:

According to Newton's second law of motion, acceleration is directly proportional to force. As the force increases (when mass is constant), the acceleration increases. This can be shown in the following formula.

[tex]f = ma[/tex]

[tex]a = \frac{f}{m} [/tex]

f = force

m = mass

a = acceleration

According to Newton's second law of motion, acceleration is directly proportional to the force.

According to Newton's second law of motion, an object's change in velocity is influenced by the force being applied to it. An object must accelerate in order to change its velocity. The rate at which an object's velocity alters over time is known as its acceleration.

Since both acceleration and force are vector quantities, the acceleration of an object is determined by the direction of the applied force. How much a net force will alter an object's velocity is described by Newton's second law of motion.

For the next twelve seconds the car slows down, and its average acceleration is For the next six seconds the car slows down further, and its average acceleration is The velocity of the car at the end of the eighteen - second period is 28.0 m/s. The ratio of the average acceleration values is a1/a2 = 1.5.

Find the velocity of the car at the end of the initial twelve - second interval.

Your answer

Answer:

30 m/s

Explanation:

To solve this, we will use Newton's first equation of motion;

v = u + at

Since we are dealing with acceleration ratio, let's make a the subject;

a = (v - u)/t

For the first 12 seconds and initial velocity u = 36 m/s, we have;

a1 = (v - 36)/12

For the remaining 6 seconds, initial velocity is the final velocity from the initial 12 seconds. Thus;

a2 = (28 - v)/6

We are given that a1/a2 = 1.5

Thus;

[(v - 36)/12]/[(28 - v)/6] = 1.5

(6/12)((v - 36)/(28 - v)) = 1.5

(v - 36)/(28 - v) = 1.5 × 12/6

(v - 36)/(28 - v) = 3

v - 36 = 3(28 - v)

v - 36 = 84 - 3v

4v = 120

v = 120/4

v = 30 m/s
