Answer:

Newtons first law of motion explains what happens in a car crash because it basically states that the passenger will continue to travel at the same velocity until an unbalanced force acts on he or she. The force that will act upon he or she would be the window, so you should always wear a seat belt!

Explanation:

According to Newtons first law of motion, a passenger tends to continue in the state of uniform motion even after the accident which causes the passenger to move forward.

According to the Newtons first law of motion, an object will continue in a state of rest or uniform motion unless it is acted upon by an external force. This is also known as the law of inertia.

While in a car undergoing uniform motion and suddenly the car is involved in an accident which causes the vehicle stop abruptly, a person suddenly moves forward because of the tendency to continue in the former state of uniform motion according to Newtons first law.

A seat belt helps to prevent the person from suddenly moving forward in a way that may lead to injury as a result of the accident.

Answer:

Ferrari would stop first.

Explanation:

The momentum of a moving body is given as:

momentum, P = mass of the body x its velocity

i. For the Freight,

mass = 5000 tons = 4535924 kg

speed = 10 mph  = 4.4704 m/s

P = mv

  = 4535924 x 4.4704

  = 20.28 x [tex]10^{6}[/tex]

P = 20.28 x [tex]10^{6}[/tex] kgm/s

ii. For the Ferrari,

mass = 3250 lb = 1474.175 kg

speed = 250 mph = 111.76 m/s

P = mv

   = 1474.175 x 111.76

   = 16.48 x [tex]10^{4}[/tex]

P = 16.48 x [tex]10^{4}[/tex] kgm/s

Comparing the momentum of the two objects, the Ferrari would stop fist when break is applied.

Answer:

The object will travel at the speed of 16 m/s.

Explanation:

Given

To determine

How fast is the object traveling?

Important Tip:

The product of the mass and velocity of an object —  momentum.

Using the formula

[tex]p = mv[/tex]

where

Thus, in order to determine the speed of the object, all we need to do is to substitute p = 64 and m = 4 in the formula

[tex]p = mv[/tex]

[tex]64\:=\:4\times v[/tex]

switch the equation

[tex]\:4\times \:v\:=64[/tex]

divide both sides by 4

[tex]\frac{4v}{4}=\frac{64}{4}[/tex]

simplify

[tex]v=16[/tex] m/s

Therefore, the object will travel at the speed of 16 m/s.

The nervous system is also known as the neural system which is basically a sophisticated network of neurons that are trained to transport information.

As we get to higher animals, the nervous system becomes more complicated. jellyfish, have very basic neural nets that run throughout their bodies. Crabs have a more complex nervous system.

The neural system in the human body combines organ activity depending on inputs detected and sent by neurons. They send out information.

Thus Option B is correct.

Answer:

Final velocity, V = 150.15 m/s

Explanation:

Given the following data;

Mass = 942kg

Net force = 6,731N

Time = 21secs

To find the final velocity of the rocket;

First of all, we would determine the acceleration of the rocket with respect to time.

Force = mass * acceleration

Substituting into the equation, we have;

6,731 = 942*acceleration

Acceleration = 6731/942

Acceleration = 7.15m/s²

Now, to find the final velocity we would use the first equation of motion.

V = U + at

Since the rocket started from rest, its initial velocity (U) is zero.

V = 0 + 7.15*21

Final velocity, V = 150.15 m/s

Explanation:

My answer to research question one is a car with a higher mass has more inertia than a car with a lower mass. A car with a higher mass needs more force to move than a car with a lower mass. The advantage of a car with greater mass is that it takes less impact when crash happens and has more protection.

The advantage of a race car with large mass is that it will continue moving without stopping once it is already in motion.

The disadvantage of a race car with large mass is that it will be difficult to get it start moving.

The Newton's first law of motion states that, an object in a state of rest or uniform motion in a straight line will continue in that form unless it is acted upon by an external force.

This first law is also known as law of inertia because it depends on mass of the object.

Inertia is reluctance of an object to move or stop moving once it is in motion.

Thus, the advantage of a race car with large mass is that it will continue moving without stopping once it is already in motion.

The disadvantage of a race car with large mass is that it will be difficult to get it start moving.

I know most of the answers will say infinity, but still this needs deeper look about its physical meaning and does it consider a practical logic?

Infinity usually used for something we could not measure, however the reality may be different!

The denominator of the equation would become 0 and the mass would become infinite if the mass's velocity ever surpassed the speed of light.

The amount of energy needed to accelerate an infinite mass would be infinite as well. The fact that light travels at the speed of c indicates that it has no rest mass.

When a mass particle approaches the speed of light, its energy grows and becomes infinite at that speed, which is why it can never be accelerated to that speed.

Experiments have confirmed this, and it has been demonstrated that nothing goes faster than the speed of light.

Answer:

Centrifugal Force = 45.65N

Explanation:

Given the following data;

Mass, m = 80kg

Radius = 487m

Velocity = 60km/h to m/s = 60*1000/3600 = 16.67m/s

To find the centrifugal force;

Centrifugal Force = mv²/r

Substituting into the equation, we have;

Centrifugal Force = 80*16.67²/487

Centrifugal Force = 80*277.89/487

Centrifugal Force = 2223.12/487

Centrifugal Force = 45.65N

Shiny metals such as copper, silver, and gold are often used for decorative arts, jewelry, and coins.

Strong metals such as iron and metal alloys such as stainless steel are used to build structures, ships, and vehicles including cars, trains, and trucks.

Some metals have specific qualities that dictate their use. For example, copper is a good choice for wiring because it is particularly good at conducting electricity. Tungsten is used for the filaments of light bulbs because it glows white-hot without melting.

Nonmetals are plentiful and useful. These are among the most commonly used:

Oxygen, a gas, is absolutely essential to human life. Not only do we breathe it and use it for medical purposes, but we also use it as an important element in combustion.

Sound is transmitted through gases, plasma or blood, and liquids as longitudinal waves, also called compression waves. It requires a medium to propagate. Through solids, however, it can be transmitted as both longitudinal waves and transverse waves.

For example, when you flick the rim of a glass, the glass will vibrate imperceptibly. These vibrations move through the air and strike the ear drum of anyone within hearing range (click here to find out 'How Our Ears Hear'). In fact, these vibrations, or sound waves, can move through any medium: gas, liquid or solid.
