The kinetic energy of an object is equal to the?

Translational kinetic energy of a body is equal to one-half the product of its mass, m, and the square of its velocity, v, or 1/2mv2.

The answer would be D. electrical energy into mechanical energy.

Explanation:

Many devices are used to convert mechanical energy to or from other forms of energy, e.g. an electric motor converts electrical energy to mechanical energy, an electric generator converts mechanical energy into electrical energy and a heat engine converts heat energy to mechanical energy.

An electric mixer is one of the many examples of devices.
