If an object weighing 90 kilograms and moving with a velocity of 20 meters per second has a kinetic energy of 4500 Joules. what is its kinetic energy when the velocity is 32 meters per second?

Kinetic energy is directly proportional to the square of velocity, so the kinetic energy will increase. If the velocity increases from 20 m/s to 32 m/s, the kinetic energy will increase by a factor of (32/20)^2 = 2.56. Therefore, the kinetic energy will be 4500 Joules * 2.56 = 11520 Joules when the velocity is 32 m/s.


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.


What will affect kinetic energy?

Kinetic energy is affected by an object's mass and its velocity. The kinetic energy of an object increases as its mass or velocity increases. Conversely, kinetic energy decreases as mass or velocity decreases.


When is the the kinetic energy the greatest?

The kinetic energy of an object is greatest when its velocity is at its maximum. Kinetic energy is directly proportional to the square of the velocity of the object, so as the velocity increases, the kinetic energy increases exponentially.


How is kinetic energy affected by a change in velocity?

Kinetic energy is directly proportional to the square of the velocity of an object. This means that as the velocity of an object increases, its kinetic energy increases exponentially. Conversely, if the velocity decreases, the kinetic energy will decrease accordingly.


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.


How much kinetic energy in a fast moving cricket ball?

The kinetic energy of a cricket ball depends on its mass and velocity. For example, a cricket ball weighing 160 grams and traveling at a speed of 140 km/h (38.89 m/s) would have a kinetic energy of about 110 joules.


What happens to kinetic energy of an object if the velocity is doubled?

If the velocity of an object is doubled, its kinetic energy will increase by a factor of four. Kinetic energy is directly proportional to the square of the velocity, so doubling the velocity results in a fourfold increase in kinetic energy.


What is the kinetic energy of the jeepney?

The kinetic energy of a jeepney depends on its mass and velocity. The kinetic energy equation is KE = 0.5 * mass * velocity^2. Given the mass and velocity of the jeepney, the kinetic energy can be calculated using this formula.


The factor that has the greatest effect on kinetic energy is?

The velocity of the object. Kinetic energy is directly proportional to an object's mass and the square of its velocity. Therefore, changes in velocity have a larger impact on kinetic energy compared to changes in mass.


What point is kinetic energy the greatest?

Kinetic energy is at its greatest point when an object is moving at its maximum velocity. This is because kinetic energy is directly proportional to the square of the velocity of an object. Therefore, the faster an object is moving, the greater its kinetic energy will be.


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.
