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 If you have four balls all traveling at 5 meters per second which one has the most kinetic energy?
All four balls would have the same kinetic energy since kinetic energy is determined by both the mass and velocity of the object. If all four balls have the same mass and velocity, their kinetic energy would be equal.
If you have a kinetic energy of 45 j and your mass is 30kg then what is your velocity?
To find the velocity, you can use the equation for kinetic energy: KE = 0.5 * mass * velocity^2. Rearranging the equation gives 45 = 0.5 * 30 * velocity^2. Solving for velocity gives velocity = √(2 * 45 / 30) = √3 = approximately 1.73 m/s.
How do you measure kinetic energy?
To calculate the kinetic energy, multiply the mass times the velocity squared and divide by 2. (Mass in kilograms, speed in meters/sec, yields energy in joules.) The equation is KE= 1/2 (mv2) Kinetic Energy= one-half (mass times velocity squared)
The mass of an object in kilograms times its velocity is?
The mass of a object in kilograms times its velocity is its momentum.
What is the energy of a system by virtue of its motion?
That's called kinetic energy. The formula is: Kinetic energy = (1/2) x mass x velocity2. If mass is in kilograms, and velocity (or speed, really) in meters per second, the energy will be in Joules.

How is kinetic computed?
Kinetic energy is calculated using the formula 1/2 * mass * velocity^2, where mass is the object's mass in kilograms and velocity is its speed in meters per second. It represents the energy an object possesses due to its motion.
What will be the kinetic energy and velocity of object of mass 62kg?
Its kinetic energy (in joules) will be (31) times (its velocity in meters per second)2 .
What is the energy stored with the motion of objects?
The energy stored with the motion of objects is called kinetic energy. It is dependent on an object's mass and speed, with the equation KE = 0.5 * mass * velocity^2, where mass is in kilograms and velocity is in meters per second.
Which object had more kinetic energy the one that has a mass of 2 kilograms or the one with the mass of 4 kilograms and was lifted at a rate of 3meters per second?
The object with the mass of 4 kilograms that was lifted at a rate of 3 meters per second would have more kinetic energy. Kinetic energy depends on both mass and velocity, so the increased mass more than compensated for the lower velocity compared to the 2-kilogram object.
How factors are used to calculate the kinetic energy of an object?
KE = (1/2)mv2 where m = mass (in kilograms), and v = velocity (in meters/second) this gives you the kinetic energy in units of Joules
What kinetic energy does a ceiling fan have?
The kinetic energy of a ceiling fan depends on its mass and the speed at which it is spinning. The formula for kinetic energy is 0.5 * mass * velocity^2, where mass is in kilograms and velocity is in meters per second. Generally, the kinetic energy of a ceiling fan is relatively low compared to other moving objects.
What is the mathmetical formula for kinetic energy?
Kinetic Energy = 1/2(mass in kilograms)(meters per second)2
What is the kinetic energy of a 8.47E plus 4 gram person moving at a velocity of 24.9 meters per second?
The kinetic energy of the person can be calculated using the formula: KE = 0.5 * mass * velocity^2. First convert the mass to kilograms (1 gram = 0.001 kg), then plug in the values to find the kinetic energy. The result will be in Joules.
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.
What is the kinetic energy of a person on a treadmill?
There is no single answer. Velocity is relative, and that means that the kinetic energy of a body also is relative. To calculate the kinetic energy you have to choose a reference frame, and the answer will be different depending on if you choose the person, the belt of the treadmill or the moon. Neither answer is more right or wrong than any other.
