Suppose an object’s initial velocity is 10 meters per second and its final velocity is 4 meters per second Mass is constant. What can best be concluded about the object based on the work-energy theorem?
Answer
A
Work is negative, the object did work on the environment, and the energy of the system decreases.
B
Work is positive, the environment did work on the object, and the energy of the system increases.
C
Work is negative, the environment did work on the object, and the energy of the system decreases.
D
Work is positive, the object did work on the environment, and the energy of the system increases.
