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.
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.
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?
KE=(1/2)mv246080 Joules
What is her kinetic energy if her mass is 70 kg and she is traveling at a rate of 6 meters per second?
Kinetic Energy = 1/2 mass kg * Velocity squared KE = 1/2mV^2 KE = 1/2(70 kg)(6 m/s)^2 = 1260 Joules
If you have a kinetic energy of 45 j and your mass is 30kg then what is your velocity?
Your velocity is 1.73 meters per second.
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

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 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 .

Kinetic Energy = 1/2 mass kg * Velocity squared KE = 1/2mV^2 KE = 1/2(70 kg)(6 m/s)^2 = 1260 Joules
If you have a kinetic energy of 45 j and your mass is 30kg then what is your velocity?
Your velocity is 1.73 meters per second.
What is the Kinetic Energy of an object with a mass of 175 Kilograms and a velocity of 3 meters per second?
Kinetic energy = 1/2(mass in kg)(meters per second squared ) KE = 1/2(175 kilograms)(3 m/s)^2 = 787.5 Joules
If a body with a mass of 88 kg is moving at a velocity of 13.89 meters per second what is it's kinetic energy?
Kinetic Energy (KE) can be represented by the following formula: KE = 0.5mv2. In this case kinetic energy would equal 8,489.0124 joules.
