Kinetic Energy = 1/2 mass kg * Velocity squared
KE = 1/2mV^2
KE = 1/2(70 kg)(6 m/s)^2
= 1260 Joules
If several objects have the same speed and the same velocity,then each has the same kinetic energy.
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.
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.
KE=(1/2)mv246080 Joules
Your velocity is 1.73 meters per second.

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.
Kinetic Energy = 1/2(mass in kilograms)(meters per second)2

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.
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.
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.
Its kinetic energy (in joules) will be (31) times (its velocity in meters per second)2 .
KE=(1/2)mv246080 Joules
Your velocity is 1.73 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
Kinetic Energy (KE) can be represented by the following formula: KE = 0.5mv2. In this case kinetic energy would equal 8,489.0124 joules.
