Assuming both pieces are traveling at 6m/s, the 4kg mass has a kinetic energy of 72 joules.

To find the kinetic energy of the 4kg mass, we first calculate the velocity of the 4kg mass by using the principle of conservation of momentum. The total momentum before the explosion is equal to the total momentum after the explosion. Once we have the velocity of the 4kg mass, we can then calculate its kinetic energy using the formula KE = 0.5 * mass * velocity^2.

What does Kinetic Energy means?
1/2 x mass x velocity x velocity. The energy possessed by moving object is called the kinetic energy.The kinetic energy of a moving body with certain velocity is equal to the work done on it to make it acquire that velocity.
The energy of matter in motion is called?
The energy of matter in motion is called kinetic energy. This type of energy is associated with an object's motion and is directly proportional to its mass and the square of its velocity.
What type of energy do rapidly moving comets have more of than slowly moving ones?
Rapidly moving comets have more kinetic energy compared to slowly moving ones. Kinetic energy is the energy of motion, and it increases with an object's velocity.
What term refers to energy that is possessed by matter due to its motion?
Kinetic energy is the term that refers to energy possessed by matter due to its motion. It depends on the mass and velocity of the object.
Derek is running a race As he approaches the finish line he speeds up How does this affect Derek's kinetic energy?
As Derek speeds up, his kinetic energy increases because kinetic energy is directly proportional to an object's velocity. Therefore, the faster Derek runs towards the finish line, the higher his kinetic energy will be.
When you have kinetic energy you must have?
When you have kinetic energy, you must have a mass and a velocity since kinetic energy is half the product of the mass and the square of the velocity.
What happends to kinetic energy when the velocity increases?
When velocity increases, kinetic energy also increases. Kinetic energy of an object is directly proportional to its velocity squared, so even a small increase in velocity can result in a significant increase in kinetic energy.
Is velocity kinetic energy?
No. This is because velocity is not a mechanical energy.
What happens to an objects kinetic energy as its velocity increases?
Kinetic Energy increases as velocity increases. Kinetic Energy = 1/2 * Mass * Velocity2
Does kinetic energy increase with speed and time?
Time is not a factor, speed is velocity and velocity equates to kinetic energy. E=Mass * Velocity squared.
What will happen to the kinetic energy for an object if its mass is double but the velocity remains at the same?
Kinetic Energy = (1/2)*(mass)*(velocity)2 If you double the mass, then the kinetic energy will double If you double the velocity, the kinetic energy will increase by a factor of 4
Does a strawberry have kinetic energy?
If the strawberry is moving, it has kinetic energy. Anything with a mass and velocity has kinetic energy.
Where velocity is squared in the kinetic energy equation doubling an object's velocity will do what to its kinetic energy?
Multiply it by 4 (4 = 22)
What two factors determine an object kinetic energy?
Kinetic energy is given by the following equaiton: KE = 0.5*m*v^2 Where KE is kinetic energy, m is the object's mass, and v is its velocity. In other words, an object's kinetic energy is dependent on its mass and the square of its velocity. Note that since the velocity term is squared, velocity has a larger effect on kinetic energy than mass. For example, if you double mass, the kinetic energy will also double, but if you double velocity, kinetic energy increases by a factor of four.
Do changes in velocity and mass have the same effect on kinetic energy?
Kinetic energy is equal to one half the mass times the square of the velocity. Thus, changes in velocity and mass do not have the same effect on kinetic energy. If you increase the mass by a factor of 10 at the same velocity, you increase the kinetic energy by a factor of 10. However, if you increase the velocity by a factor of 10 at the same mass, you increase the kinetic energy by a factor of 100.
The kinetic energy of the object moving with a velocity of 5 meter per second is 25 joules. What will be the kinetic energy when the velocity is tripled?
When the velocity is tripled to 15 meters per second, the kinetic energy will increase by a factor of 9 (3^2) since kinetic energy is proportional to the square of velocity. So, the kinetic energy will be 225 joules (25 * 9) when the velocity is tripled.
How do you solve the time by the given of mass and kinetic energy?
To solve for time using mass and kinetic energy, you would need more information. Kinetic energy depends on both mass and velocity, while time is a measure of the duration of an event. Without knowing the velocity or distance traveled, it is not possible to directly calculate time from mass and kinetic energy.
