Interpretation:
The velocity of the given object should be calculated in the given statement by using the equation of kinetic energy
Concept Introduction:
Energy is the ability to do work or transfer heat where work is the movement of a body using some force. The SI unit of energy is joule (
Where,
Thermal energy is the internal energy of an object due to the kinetic energy of its atoms and/or molecules. The atoms and/or molecules of a hotter object have greater kinetic energy than those of a colder one, in the form of vibrational, rotational, or, in the case of a gas, translational motion. For example, a hot brick has a greater kinetic energy than a cold brick.
To calculate: Calculate the velocity (in
