An object's kinetic energy is the power it draws from movement. It is described as the amount of effort required to accelerate a body of a specific mass from rest to its specified velocity. The body keeps its kinetic energy after gaining it during acceleration, barring changes in speed. When slowing down from its current pace to a condition of rest, the body expends the same amount of energy. Any term in a system's Lagrangiam that has a derivative with respect to time is formally referred to as having kinetic energy.

(round your answer to two decimal places.)
A block of mass 0.260 kg is placed on top of a light, vertical spring of force constant 5 025 n/m and pushed downward. After the block is released, the spring will travel upward to the maximum height of 10.86 meters.
The relation between the potential energy on a string and the length it stretches is given by:
E = 1/2 . kx²
Where:
k = spring constant
x = spring stretch or compression
In the given problem:
k = 5,025 N/m
x = 0.106 m
Hence,
E = 1/2 . 5025 . (0.106)²
m . g . h = 1/2 . 5025 . (0.106)²
Where;
m = mass
h = height from the release point.

va car with a mass of 950-kg and a speed of 22 m/s approaches the intersection from the west. a 1300-kg minivan traveling 15 m/s approached the intersection from the south. after the collision two cars move together. what is their speed and direction of the velocity?
The final speed of the car and minivan is 17.95 m/s
The mass of the car = 950 kg
The speed of the car = 22 m/s
The mass of the minivan = 1300 kg
The speed of the minivan = 15 m/s
The final speed of the car and minivan can be found using the conservation of momentum formula,
[tex]\displaystyle m_{1}v_{i1 } + m_{2}v_{i2} = m_{1}v_{f1} + m_{2}v_{f2}[/tex]
where [tex]\dispplaystyle m_{1}[/tex] is the mass of the car
[tex]\dispplaystyle m_{2}[/tex] is the mass of the minivan
[tex]\dispplaystyle v_{i1}[/tex] and [tex]\dispplaystyle v_{i2}[/tex] is the initial speed of the car and minivan respectively.
[tex]\dispplaystyle v_{f1}[/tex] and [tex]\dispplaystyle v_{f2}[/tex] is the final speed of the car and minivan respectively.
As the two cars move together, they would have the same final speed, i.e.
[tex]\dispplaystyle v_{f1} = \dispplaystyle v_{f2} = \dispplaystyle v_{f}[/tex]
Thus, the above equation becomes,
[tex]\displaystyle m_{1}v_{i1 } + m_{2}v_{i2} = (m_{1} + m_{2})v_{f}[/tex]
Let us substitute the known values in the above equation, we get
(950 x 22) + (1300 x 15) = (950 + 1300) [tex]\displaystyle v_{f}[/tex]
20,900 + 19.500 = 2,250 [tex]\displaystyle v_{f}[/tex]
40,400 = 2,250[tex]\displaystyle v_{f}[/tex]
40,400 / 2,250 = [tex]\displaystyle v_{f}[/tex]

How do plates move in relation to each other at convergent boundaries?
When plates commute in the exact direction it collides, and the plates move to other at convergent boundaries.
The lighter, dense, and much more elastic oceanic plate dips underneath the thicker, more stiff continental plate whenever a continental plate encounters a marine plate.
It's known as subduction. Deep ocean trenches, like the one that runs down South America's west coast, are created by subduction.
The continent's undercut rocks start to melt. On occasions, a chain of eruptions forms as the hot magma rises to the surface and travels through the continent.
Nearly 80% of earthquakes happen along convergent borders when plates are being pushed together.
Destruction, when two continental plates crashes, is just another kind of convergent boundary. The plates collapse and are propelled upward since neither is heavier compared to the other.

a proton moves in the direction shown in a uni- form magnetic field. at this instant, which arrow points in the direc- tion of the force on the proton by the magnetic field?
When the proton starts to move upward the direction of the magnetic force changes and when the proton moves straight up the magnetic force turns to the left.
The direction of the force is perpendicular to the direction of the magnetic field and current, as given by Fleming's left-hand rule. Here the magnetic field is to the right and the direction of the current is upward. Protons feel a force on themselves due to the magnetic field. The force on the proton is proportional to the proton's magnetic flux density and velocity.
The velocity and momentum of a proton are affected by the force acting on it. If the velocity of a charged particle is perfectly parallel to the magnetic field, the magnetic field exerts no force on the particle, so the velocity remains constant. The momentum of a proton moving freely in a magnetic field is the product of the proton's mass and the proton's velocity. As the speed of a proton moving in a magnetic field changes, so does the momentum of the proton.

The intensity of the sound at a distance of 0.40 m from the source is 0,398 W/m²
Sound wavesSound waves are classified as a longitudinal wave where the direction of propagation is parallel to the direction of vibration.
Sound intensity is formulated as follows:

(a) determine the magnitude of the force from the ground on each front wheel (assuming equal forces on the front wheels). 2665.79 correct: your answer is correct. n (b) determine the magnitude of the force from the ground on each rear wheel (assuming equal forces on the rear wheels).
The magnitude of the force from the ground on each front wheel is 2775N.
Let us call the force on the front axle F and the force on the rear axle R.
We know that
⇒ F + R= total weight of vehicle = 1360 * 9.80 = 13328 Newtons
And using torques, you know that force on the front axle * distance to the center of mass = force on the rear axle * distance to the center
of mass
or F *1.78 = R * (3.05 - 1.78)
So
1.4016F = R
Then.
F + 1.4016 F = 13328
F = 5550 N and R = 13328 - 5550 = 7778N
So the force on each front tire is 5550 /2 = 2775N
And the force on each rear tire is 7778 /2 = 3889N

Inelastic collisions are the collisions in which the kinetic energy is lost. The momentum of the system is conserved in inelastic collisions, but kinetic energy is not. This is because some of the kinetic energy was transferred to another.
Suppose two similar cars are approaching. They collide, but the sled is equipped with a magnetic clutch so that when they collide they combine into a single agglomerate.

a longitudinal wave is observed. Exactly 6 crests are observed to move past a given point in 9.1 s. Its wavelength is 2.4 m and its frequency is 0.66 HZ. What is the speed of the wave.
The speed of the longitudinal wave is given or computed as 1.584 or approximately 1.6m/s.
What is a wave?A wave is a propagating dynamic disturbance of one or more variables in physics, mathematics, and related sciences. Periodic waves occur when values oscillate repeatedly about an equilibrium value at a certain frequency.
Longitudinal waves are those in which the medium's vibration is parallel to the wave's travel direction and the medium's displacement is parallel to the wave's propagation direction.
A longitudinal wave is an example of one. P-waves of ultrasonography from earthquakes
Compression, rarefaction, wavelength, amplitude, period, and frequency are all important characteristics of a longitudinal wave.
To estimate the above answer multiply wavelength and frequency to get the speed of a wave.
That is:
2.4 x 0.66
= 1.584
If the frequency is not given, one can divide 6 crests by 9.1 seconds to determine the frequency.

What is the velocity of a 1.2 kg ball rolling with a momentum of 15.6 kg m/s?
Answer:
Velocity V = 13 m/s
Explanation:
Given:
m = 1.2 kg
p = 15.6 kg·m/s
__________
V - ?
Momentum:
p = m·V
Velocity:
V =p /m = 15.6 / 1.2 ≈ 13 m/s
