The formula for kinetic energy is KE = 1/2 x m x v2 where m is the mass measured in kg and v is the velocity measured in m/s.
We are given that m = 500.0 kg and that v = 35.0 m/s.
Thus, KE = 1/2 x 500.0 kg x (35.0 m/s)2 = 306250 J or 3.06 x 105 J if you are using significant figures.
(Note that 1 J = 1 kg m2/s2.)

Ek=1/2(18kg)(25m/s)2

What are factors that affect an object's kinetic energy?
The factors affecting kinetic energy are mass and velocity.
What does the amount of kenetic energy that a moving object has depend on?
The amount of kinetic energy an object has depends on its mass and speed.
Is kinetic energy a form of energy in the earth's system?
No, not at all. Kinetic energy is energy related to movement - any moving object has kinetic energy; at low (non-relativistic) speeds, the kinetic energy is calculated as 0.5 x mass x velocity squared.No, not at all.

What two factors determine the kinetic energy of moving object?
velocity and mass
What is kinetic energy-?
Kinetic energy is energy that is posessed by a moving mass.
What does the amount of kinetic energy of a moving object depend?
The kinetic energy depends on the object's mass, and on its speed.
What are factors that affect an object's kinetic energy?
The factors affecting kinetic energy are mass and velocity.
Why does a moving object gain mass?
Mass is the sum of energies, both kinetic and potential. As the velocity increases so does the kinetic energy of object.
What objets has kinetic energy?
kinetic energy is the energy an object has by virtue of its motion- therefore any object that is moving possesses kinetic energy ( and the kinetic energy is proportional to both the mass of the object and the object's velocity, according to the equation KINETIC ENERGY= 1/2 mv2)
What does the amount of kenetic energy that a moving object has depend on?
The amount of kinetic energy an object has depends on its mass and speed.
What form of energy do all moving objects have?
potential energy, heat energy, kinetic energy, or random energy.......

What two factors determine how much kinetic energy a moving energy?
Do you mean "a moving object"? Then the answer is mass & speed.
What 2 factors does the kinetic energy depend on?
It depends on mass and velocity. ans : it depends on the mass & speed of the moving object. no, it depends on the work & energy.
The energy an object has because it is moving?
Kinetic energy is the energy that an object has because of its motion. The energy depends on the speed and mass of the object.
What two factors determine the kinetic energy of moving object?
velocity and mass
Which two factors can be caclulated to determine the kinetic energy of an object?
The kinetic energy of any moving object is one-half the product ofthe object's mass and the square of its speed.
