Nikhil bought a large plant in a planter for his mother. He took it home and pushed it around his living room until he found a good location for it near the window. After he watered the plant, he was very surprised how difficult it was to push the planter. Based on Newton’s second law, why does it become more difficult to move the planter? Choose the three statements that apply.
A. With the water, the planter had more mass and more inertia.
B. Nikhil had to apply more force to produce the same acceleration.
C. Increased inertia means that less force is needed to move the planter.
D. If Nikhil used the same amount of force, the acceleration of the moving planter would be less after adding the water.
