Kinetic energy is an
expression of the fact that a moving object can do work on anything it hits; it
quantifies the amount of work the object could do as a result of its motion. It
can be calculated as:
KE
= mv^2 /2
We
calculate the problem as follows:
KE
= mv^2 /2
400
= m(20)^2 / 2

Explanation:
Mass and energy are closely related. Due to mass–energy equivalence, any object that has mass when stationary (called rest mass) also has an equivalent amount of energy whose form is called rest energy, and any additional energy (of any form) acquired by the object above that rest energy will increase the object's total mass just as it increases its total energy. For example, after heating an object, its increase in energy could be measured as a small increase in mass, with a sensitive enough scale.
