Mass (given total work, initial and final velocity)
mass of the object
initial velocity of the object
final velocity of the object
In physics, work is the amount of energy transferred by a force acting through a distance in the direction of the force. According to the work-energy theorem, if one or more external forces act upon a rigid object, causing its kinetic energy to change from Ek1 to Ek2, then the mechanical work (W) done by the net force is equal to the change in kinetic energy.
