An object of mass m is moving with a constant velocity `upsilon` How much work should be done on the object in order to bring the object to rest ?

Explanation

Kinetic energy of an object mass, moving with a velocity, v is given by the expression,
`E_(k) = 1//2 mv^(2)`
The bring the object to rest, `1//2 mv^(2)` amount of work is required to be done on the object.
