Suppose an object's initial velocity is 10 m/s and its final velocity is 4 m/s. Mass is constant. What can best be concluded about the object based on the work-energy theorem?
Ο Ο Ο Ο
Work is positive, the environment did work on the object, and the energy of the system increases.
Work is positive, the object did work on the environment, and the energy of the system increases.
O Work is negative, the object did work on the environment, and the energy of the system decreases.
