Answer:

100 N

Explanation:

For ONE bullet ( .025 kg)

 fired to 1000 m/s   in  .25 s   ( four per second)

     acceleration = 1000 m/s   /  .25 s = 4000 m/s^2

then F = ma

           = .025 kg * 4000 m/s^2 = 100 N

Velocity with which the object hits the ground will be  22.3 m/sec.

Velocity is the rate of change of distance with respect to time.

According to the third equation of motion, it relates final velocity with the initial velocity and acceleration

Mathematically, v² = u² + 2as

s = 25 m

a = g = acceleration due to gravity because the object is falling towards the ground = 9.8 m/sec²

u = initial velocity = 0 m/s

v = final velocity = which is to be calculated

v² = u² + 2as

v² = 0 + 2 x 10 x 25

v² = 500

v = [tex]\sqrt{500}\\[/tex]

v = 22.3 m/sec

Velocity of the object will be 22.3 m/sec when it will hit the ground.

This means that the ball does not have any velocity when it is at the spring's equilibrium position.

Equilibrium is a state of balance where opposing forces or influences are equal and balanced. It is a situation where there is no tendency for change in a system. Equilibrium can be reached in a variety of situations in economics, physics, chemistry, biology, and other fields. In economics, equilibrium is the state at which the market prices of goods and services are stable and consistent with the amount of goods and services that are being supplied and demanded. In physics, equilibrium is a state where all forces acting on an object are balanced and no net force is present. In chemistry, equilibrium is a state where the rates of the forward and reverse reactions of a chemical reaction are equal. In biology, equilibrium is a situation where the forces of natural selection are balanced and no net change in the genetic composition of a population is observed.

The muzzle velocity of the ball can be calculated using the equation v = √2gy,
Where v is the velocity of the ball, g is the acceleration due to gravity, and y is the height of the spring's equilibrium position.
In this case, the muzzle velocity of the ball is equal to √2g*0, or 0 m/s, since the spring's equilibrium position is at y=0.

Answer: 12,100 Joules of Kinetic Energy

Explanation:

Kinetic energy is a measure of how much energy something has because it's moving. To calculate the kinetic energy of a bike, you need to know how heavy it is and how fast it's going. We use a formula that looks like this:

(1/2) x the weight of the bike (in kilograms) x the speed of the bike (in meters per second) x the speed of the bike (in meters per second)

So if we have a bike that weighs 25 kilograms and is going 22 meters per second, we can plug those numbers into the formula like this:

(1/2) x 25 x 22 x 22

And we find out that the bike has 12,100 Joules of kinetic energy.

40 m/s

We have the equation of motion v^2-u^2= 2as ------------- ( i)

where v = final velocity which is unknown let it be x m/s

u = initial velocity which is 0 m/s ...( The body starts from rest )

a = Acceleration gained by body = 8 m/s^2

s stands for distance covered in till v velocity which is 100 meters.

Range formula:

R = V^2 sin 2θ / g

sin 2θ = R g / V^2 = 80 m * 9.80 m/s^2 / (30 m/s)^2 = .871

2θ = 60.6 deg

θ = 30.3 deg

Check:     30 * cos 30.3 = 25.9 m/s       horizontal speed

t = 80 m / 25.9 m/s = 3.08 sec        to reach target

H = Vy0 t - 1/2 g t^2

Vy0 = 30 * sin 30.3 = 15.1 m/s     initial vertical speed

H = 15.1 * 3.08 - 4.9 * 3.08^2 = 46.5 - 46.5 = 0    

Ball will be back at starting height after 3.08 s

The ball continues to fall, its kinetic energy will increase.

Kinetic energy is the energy an object possesses due to its motion. It is the energy associated with an object’s speed and mass, and is the energy that an object has because of its movement. Kinetic energy can be converted into other forms of energy, such as heat, light, or sound. It can also be used to do work, such as moving objects or powering machines. Kinetic energy is a form of mechanical energy, which is energy that is associated with the motion or position of an object. Kinetic energy is related to the work done on an object, and it increases as the object’s speed increases. Kinetic energy can be calculated using the formula KE = ½mv2, where m is the mass of the object and v is the velocity of the object.

The kinetic energy of the ball will increase as it falls, because it is gaining speed due to gravity.
As it falls, it accelerates at a rate of 9.8 m/s^2, and its kinetic energy is equal to its mass multiplied by the square of its velocity.
Therefore, as the ball continues to fall, its kinetic energy will increase.

Answer:

To solve for the voltage drop at V₁, we can use Ohm's law, which states that the voltage drop across a resistor (V) is equal to the current (I) flowing through it multiplied by the resistance (R) of the resistor.

V = I * R

The information given in the question is as follows:

VT = 101.00 V

T = Unknown

R₁ = Unknown

V₁= Unknown

I₁=Unknown

R₂= Unknown

V₂= 33.00 V

I₂ = 12.00 Amperes

R₂ = Unknown

V₃ = 37.00 V

I₃ = 13.00 Amperes

R₃ = 12.00 Ohms

The first step is to calculate the current flowing through the circuit by using the formula Power= Voltage * Current

P = VT

I = P/VT = 101/101 = 1 Amperes

Now we can use Ohm's Law to find the voltage drop across R1:

V₁ = I * R₁ = 1 * R₁

To find the resistance of R1, we can use the formula:

T = V₁ + V₂ + V₃

R₁ = (T - V₂ - V₃) / I

Substituting the values,

101 = V₁ + 33 + 37

V₁ = (101 - 33 - 37) = 31 Volts

So, the voltage drop at V₁, which is the voltage drop at resistor one, is 31 Volts.

Answer:

Magnetic energy can be transformed into kinetic energy in a variety of ways.

Explanation:

One way that this occurs is through electromagnetic induction. This occurs when a changing magnetic field induces an electric current in a conductor, such as a wire. This induced current creates a force that can move the conductor, thus transforming the magnetic energy into kinetic energy. This process is used in electric generators, which convert the kinetic energy of a turbine into electrical energy by turning a coil of wire inside a magnetic field.

Another way that magnetic energy can be transformed into kinetic energy is through the operation of an electric motor. An electric motor uses the interaction between a magnetic field and an electric current to create a force that can rotate a shaft, thus transforming the electrical energy into kinetic energy. Electric motors are used in a wide range of applications, including transportation, manufacturing, and household appliances.

Magnetic energy can also be transformed into kinetic energy through magnetohydrodynamics (MHD), which involves the interaction of a fluid with a magnetic field. When a fluid such as a gas or liquid moves through a magnetic field, it can generate a force that can propel the fluid, thus transforming the magnetic energy into kinetic energy. This process is used in some forms of propulsion, including maglev trains and MHD generators.

In summary, magnetic energy can be transformed into kinetic energy through the interaction of a magnetic field with a conductor, an electric current, or a fluid, which creates a force that can move an object, thus transforming the magnetic energy into kinetic energy.
