Time = distance / velocity

52.1 meters / 18.5 m/s = 2.82 secondsT

The kinematics and Newton's second law allow us to find the height from which the block system descends is:

             y = 6.54 m

Given parameters

To find

Newton's second law gives a relationship between the net force, the mass, and the acceleration of the body.

      ∑ F = m a

Where the bold letters indicate vectors, F is the force, m the mass and the acceleration of the body.

Kinematics studies the movement of bodies, looking for relationships between position, velocity and acceleration

              y = v₀ t + ½ a t²

In the attached we have a free body diagram of the system, let's write Newton's second law.

          T - W₁ = m₁ a

         -T + W₂ = m₂ a

Let's solve the system of equations.

          W₂ - W₁ = (m₁ + m₂) a

          a = [tex]\frac{m_2-m_1}{m_2+m_1} \ g[/tex]

Let's calculate

          a = [tex]\frac{2 -4}{ 2 +4} \ 9.8[/tex]  

          a = -3.27 m / s²

The negative sign indicates that the heaviest body is descending.

Now we can use kinematics to find the height, as the system comes out of rest the initial velocity is zero, when he reaches the ground his height is zero.

             y = y₀ + v₀ t + ½ a t²

             0= y₀ + 0  +½ a t²          

Let's calculate

             y₀ = ½ 3.27 2²

             y = 6.54 m

In conclusion, using kinematics and Newton's second law we can find the height from which the block system descends is:

             y = 6.54 m

Answer:

C 01.5

i calculated and it was right

pls ignore the first answer

it was mistake

The only part of the diagram that remains is the force that moves the object forward which is 50 N.

We know that the net force is obtained using the relation;

Net force = -Frictional force + Rightward force

The frictional force is negative because its direction is opposite to that of the forward force.

We have the following information from the question;

Frictional force = 30 N

Rightward force = 80 N

Mass = 5.00 kg

Net force is obtained from;

5a = 80 - 30

5a = 50

a = 10 m/s^2

Net force  = 50 N, This the force that moves the object forward.

Astronomers are known to estimate the distance of nearby objects in space through the use of stellar parallax, or trigonometric parallax.

They often measure a star's  movement using the background of more distant stars as Earth revolves around the sun.

With the use of Parallax, one can get the best way to have the distance in astronomy,

Triangulation is often used instead of parallax to know the terrestrial distances by forming triangles with a predefined base and measuring the angles formed with the other two sides.

Answer:

I think the correct answer is B

A collision which is inelastic is one in which the internal energy changes.

All the kinetic energy is dissipated

Reasons:

The given parameters are;

The mass of one car = The mass of the second car in the collision = m

The type of collision = Inelastic collision

The speed of each of the cars in the collision = v and -v

Solution:

In an inelastic collision, we have;

[tex]m_1 \cdot v_{1i} + m_2 \cdot v_{2i} = (m_1 + m_2) \cdot v_f[/tex]

Therefore, we get;

[tex]m \cdot v_{i} -m \cdot v_{i} = 0= 2 \cdot m \cdot v_f[/tex]

Which gives;

[tex]v_f = 0[/tex]

The collision is an example of a perfectly inelastic collision, and the final velocity after the collision is zero.

The change in the energy is [tex]\Delta K.E. = K.E._{final} - K.E._{initial}[/tex]

[tex]K.E._{initial}[/tex] = 0.5·m·v² + 0.5·m·v² = m·v²

ΔK.E. = 0.5·(2·m)×0 - 0.5·m·v² + 0.5·m·v² = -m·v²

ΔK.E. = -m·v²

The negative sign stands for energy given out, which gives;

The energy dissipated = m·v² (The total initial kinetic energy)

Therefore, all the kinetic energy is dissipated

Radio waves and gamma rays traveling in space have the same speed in free space.

Hope this helps!!

Radio and Gamma rays travel with the same speed in free space.

"Both are electromagnetic waves. Both the waves travel with the speed 3 x 10^8 m/s in free space. Radio waves have low frequency but high wavelength. Gamma waves have very high frequency but small wavelength. Hence Radio and Gamma waves both travel with the same speed in free space."

Explanation:

Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.

Answer:

Kinetic energy = (1/2) (mass) (speed)²

Kinetic energy = (1/2) (8 kg) (4 m/s)² =

                                 (4 kg) (16 m²/s²) =

                                  64  (kg-m/s²) (m) = 64 newton-m = 64 joules

A cat of mass 8 kg moving with a velocity of 4 m/s, then the momentum of the cat's movement will be equal to 32 kg m/s.

The momentum is the result of a particle's velocity and its mass. Force and motion, meaning it has both magnitude and the direction. According to Isaac Newton's second equation of motion, the force acting on a particle equals the time rate of increase of momentum.

The impulse, which is the product of the force and the intervals (the impulse), is equal to the difference in momentum, according to Newton's 2nd law, if a steady force operates on a particle for a specific amount of time. On the other hand, a particle's momentum is the amount of time needed for a consistent action to fight it to rest.

As per the data provided in the question,

Mass of the cat, m = 8 kg

Velocity of the cat, v = 4 m/s.

[tex]Momentum(p) = Mass(m)*velocity(v)[/tex]

p = (8 kg) × (4 m/s)

p = 32 kg m/s.

Therefore, the momentum of the cat is 32 kg m/s.

Kinetic energy is energy that possesses due to its motion. Basically, a moving object has kinetic energy.

Potential energy is the energy held by an object due to its position relative to other object. Which means it has the possibility (potential) to become kinetic energy, but at that moment where it’s not moving, it’s potential energy.

According to the characteristics of non-metals such as nitrogen and phosphorous  which are solids they are also brittle.

Non-metals do not possess luster and are dull . They are not malleable and ductile and are soft due to the covalent bonding present in them . Non-metals on the other hand owing to their soft nature have low melting points.

Non-metals have four to seven valence electrons owing to which they usually form covalent bonds. They are poor conductors of heat and electricity  and are mostly in liquid or gaseous state.They are widely used in the manufacture of fertilizers , in rocket fuels and in the form of graphite in pencil leads.

Non-metals have high ionization energies  and high electronegativities.
