What is the kinetic energy of an object that has a mass of 30 kilograms and moves with a velocity of 20 m/s?
2 Answers
Explanation:
Kinetic energy of an object is given by the equation
where
So, plugging in our given values into the equation, we get
Now, we know that
Also, we can convert it to kilojoules by dividing by one thousand, and so we have:
6000 Joules
Explanation:
For this formula, always use kilograms as your unit of mass and m/s for your unit of velocity. This will yield a unit of Joules.
Don't forget your units!
