Which has the most kinetic energy a 1000 kg car traveling 30 ms or a car traveling 45 ms?
WOW, 5 MILES PER SECOND. I guess that I would have to calculate the miles per hour. To do this, we must multiply 5 miles per second times 3600(the number of seconds in an hour). That is 18000 miles per hour. I like to work in the SI system, so by converting this to meters per second, we get 8.04672E3 meters per second. Kinetic energy is defined as one half mvsquared. The Kinetic Energy is equal to 3.2374E10 Joules.
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.
Is touching a kinetic energy?
Kinetic energy is the energy of motion. Your touching finger has mass and is moving some meters per second, so that motion is kenetic energy.
Is a joule meters per second by kg?
No, a joule is the unit of energy, equivalent to one watt-second. It represents the amount of energy transferred or converted within a system. On the other hand, meters per second per kg is the unit of specific kinetic energy, representing the kinetic energy per unit mass of an object moving at a certain velocity.
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.
How much kinetic energy does an electron traveling in free space at 32415.926535 ms have?
You are supposed to use the formula for kinetic energy. As a reminder, the formula is (1/2)mv2. If the speed is in meters per second, and the mass in kilograms, the energy will be in joules.
What is the mathmetical formula for kinetic energy?
Kinetic Energy = 1/2(mass in kilograms)(meters per second)2

How many joules of kinetic energy does a 750 kg car traveling at 65 mi hr have. By what factor would its kinetic energy decreases if the car travel half as fast?
For this question, we will use the formula K = 1\2 mv2. But first, we must convert the 65 miles per hour into meters per second. Multiply miles per hour by a factor of 1.609 to get kilometers per hour. Divide this answer by 3600 to get kilometers per second. Multiply this by 1000 to get meters per second. In this case, the velocity in meters per second is aproxamitely 29 meters per second. To get the kinetic energy, we multiply one half, times the mass 750 kg, times 292 meters per second. This yields 315375 Joules. If we halved the velocity, the kinetic energy would be one-fourth that of the original kinetic energy. This is because the velocity is squared. This holds true if we go to one third the original speed. Then it would be one-ninth of the original kinetic energy.
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 .
Is touching a kinetic energy?

How do you convert electric potential energy (ev) to meters per second (m/s)?
To convert electric potential energy (eV) to meters per second (m/s), you can use the formula: 1 eV 1.602 x 10-19 joules. Then, you can use the formula for kinetic energy: KE 0.5 m v2, where KE is the kinetic energy, m is the mass, and v is the velocity in meters per second. By equating the electric potential energy to the kinetic energy, you can solve for the velocity in meters per second.
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.
Is a joule meters per second by kg?
No, a joule is the unit of energy, equivalent to one watt-second. It represents the amount of energy transferred or converted within a system. On the other hand, meters per second per kg is the unit of specific kinetic energy, representing the kinetic energy per unit mass of an object moving at a certain velocity.
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.
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.
