What happens to the kinetic energy of a body when: a) the mass of the body is doubled at constant velocity? b) the velocity of the body is doubled at constant mass? c) the mass of the body is doubled but the velocity is reduced to half?

12000j is work done

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
