The required speed of the centre of mass of the two-railcar system after the collision will be half as much as it was before the collision.

One of the railroads has zero motion prior to the collision. Following it, both railroads move at the same speed. By the conservation of the total momentum of the system, we have,

m vi = m vf + m vf

m vi = 2 m vf

vi = 2 vf

vf = 1/2 vi

vf is the velocity after collision

vi is the velocity before collision

Thus, the speed of the railroad together after the collision is calculated to be half of that before collision.

Explanation:

If there is no friction and block B pushes block A with a force of magnitude F, therefore FA will also have a magnitude F, according to Newton's third law of motion.

According to Newton's third law, each force (action) in nature has an opposite and equal response. Whenever object B pulls on object A, item A pulls back on item B with an equal and opposing force.

Given :

Mass of Block A = M

Mass of Block B = 3M

Force exerted on block A is FA

Because both boxes are in contact.

Hence, force exerted by block A on block B is same that is FA

Force exerted by block B on block A has magnitude F (Given)

"A notch is a distortion in a voltage waveform where the voltage quickly drops toward zero and then returns to the correct value."

In general, the primary overcurrent device is not considered to safeguard transformer secondary wires. Transformers with two windings are all isolation transformers.

A voltage waveform distortion known as notching is brought on by intense current bursts of very short duration. These distortions generally show up graphically as a notch in the waveform's time domain representation.

When current commutates from one phase to another during normal operation of power electronic devices, a sort of periodic waveform distortion called voltage notching is created. The most significant instance of voltage notching occurs in three-phase converters. The transition of the current from one phase to another causes the notches.

Answer:

Explanation:

The mean free path between collisions is 1.41 mm.

The mean free path between collisions in a gas can be calculated using the formula: mean free path = 1 / (density x collision cross-section)

To calculate the mean free path between collisions for the ping-pong balls, we first need to calculate the number density of the balls, which is the number of balls per unit volume. Since the box is 1m x 1m x 1m, and the diameter of a ping-pong ball is 0.03m, the volume of the box is 1m^3 and the volume of a single ball is 4/3 * pi * (0.03/2)^3 = 2.5*10^-5 m^3.

Therefore, the number density of the balls is 2000 / 1 = 2000 balls/m^3.

The collision cross-section of a sphere is given by the formula:

cross-section = pi * (diameter / 2)^2

So, the collision cross-section of a ping-pong ball is pi * (0.03 / 2)^2 = 7.07 * 10^-4 m^2

Therefore, the mean free path between collisions is:

mean free path = 1 / (2000 x 7.07 * 10^-4) = 1.41 * 10^-3 m or 1.41 mm

This means that the ping-pong balls in the lottery machine are colliding on average every 1.41mm.

a)  ω = 8.75 rad/s

b) I = 12.9 kgm^2

Explanation:

Given data:

Radius of the wheel r = 0.400 m

Speed of the suitcase v = 3.50 m/s

Height h = 4.00 m

Mass of the suitcase m = 15 kg

a) To determine angular velocity of the wheel when the suitcase reaches the ground is

we know that ,         ω = v / r

ω = (3.50 m/s) / (0.400 m )

    ω = 8.75 rad/s

b) From the conservation of energy

  we have         KEi + Ui = KEf + Uf

where KEi , KEf are initial and final kinetic energies and Ui and Uf are initial and final potentail energies.  

We know that KEi = 0 and Uf   = 0

             Ui = KEf

           mgh = (1/2)mv^2 + (1/2) Iω^2

I = moment of inertia of wheel to determined

15×9.8×4 = (1/2) (15)(3.5)^2 + (1/2) I (8.75)^2

Calculating we get                  

I = 12.9 kgm^2

A force that acts on a body moving in a circular path and is directed toward the center around which the body is moving.

According to the question, The formula is used to find the omega is:-

[tex]w =\frac{v}{r}[/tex]

[tex]w= \frac{3.50}{0.400}[/tex]

Hence, the omega is ω = 8.75 rad/s

From the conservation of energy  we have  KEi + Ui = KEf + Uf

where Kei, KEf are initial and final kinetic energies and Ui and Uf are initial and final potential energies.  

We know that KEi = 0 and Uf   = 0

So, therefore the Ui = KEf

Hence [tex]mgh = \frac{1}{2}mv^{2} + \frac{1}{2} Iw^{2}[/tex]

After putting the value:-

[tex]15*9.8*4 = \frac{1}{2}*15*3.5^{2} + \frac{1}{2}*I*8.75^{2}[/tex]

Answer:

i) El período de la rueda es de 0,25 segundos.

ii) La frecuencia de la rueda es 4 Hertz

iii) La velocidad angular es aproximadamente 25.133

iv) La velocidad lineal es de aproximadamente 3,77 m / s

Explanation:

El radio de la rueda, r = 15 cm = 0,15 m

El número de vueltas que hace la rueda = 64 vueltas

El tiempo que tarda el volante en dar 64 vueltas = 16 segundos

i) El período = El tiempo que tarda la rueda en dar 1 vuelta

∴ El período de la rueda, T = 16 segundos/(64 vueltas) = 0,25 segundos

El período de la rueda, T = 0,25 segundos

ii) La frecuencia = El número de vueltas por segundo

∴ La frecuencia de la rueda, f = 64 vueltas /(16 segundos) = 4 Hertz

1 vuelta = 2 · π radianes

La frecuencia de la rueda, f = 4 Hertz

iii) Velocidad angular = La medida del ángulo girado por segundo

∴ La velocidad angular, ω = 64 × 2 × π/16 segundos ≈ 8 · π rad/segundos ≈ 25.133 rad/seg

La velocidad angular, ω ≈ 25.133

iv) La velocidad lineal, v = r × ω

La velocidad lineal, v ≈ 3.77 m/s

Option B is V2/Mg  gives the total distance travelled by the mass before it is slowed to a stop by friction

The total distance traveled by the mass before it is slowed to a stop by friction can be determined by calculating the work done by the force of friction on the mass. As we have seen before, the force of friction acting on the mass is given by the equation F = friction = umg.

Now, the work done by the force of friction on the mass is given by W = Fd. Using the definition of force of friction and assuming that the final velocity of the mass is zero, we can write the following equation:

umgd = (1/2)mv^2

Dividing both sides by m*g and simplifying the equation we get:

d = (1/2) * u^-1 *v^2 /g

If we compare this expression with the options provided, we can see that it matches with option B: V^2/Mg. Therefore, the total distance traveled by the mass before it is slowed to a stop by friction is given by V^2/Mg.

The correct option is B, the sound that reaches the ears after bouncing off a wall or a floor is called indirect sound.

Indirect sound is a type of sound that is not heard directly by the listener. Instead, it is heard through reflections of the original sound off of nearby surfaces. This sound is more muffled, as the reflections tend to lose some of the original sound's energy as it is reflected from wall to wall. Indirect sound is often used in recording studios and concert halls, as it can create a more natural or realistic sounding environment.

This is due to the fact that in real life, the sound is rarely heard directly by the listener, but rather bounces off of nearby surfaces. By using indirect sound, a more natural sound can be created for the listener. Indirect sound is also used in sound reinforcement systems, as it can help distribute sound more evenly throughout a space. This can help to create a more uniform sound.
