Question

in the apple - pulling - the orange sequence in this chapter, what is the force that accelerates the system across the floor? view available hint(s) the backward pull by the orange internal forces friction between the apple and the floor the resistance to motion by the orange

Explanation:

Internal forces within a system do not cause the system as a whole to accelerate. The backward pull by the orange and the resistance to motion by the orange are internal - reaction forces. Friction between the apple and the floor is an external force that can act on the apple - orange system to accelerate it across the floor.

Answer:

C. Friction between the apple and the floor
