Question 6 of 12 • PBCSD_Grade_Forgiveness_2003310_Physical Science_S2_2022

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?

Answer
A
Work is positive, the environment did work on the object, and the energy of the system increases.
B
Work is positive, the object did work on the environment, and the energy of the system increases.
C
Work is negative, the object did work on the environment, and the energy of the system decreases.
D
Work is negative, the environment did work on the object, and the energy of the system decreases.
