Answer:
5 pounds of force in the opposite direction
Step-by-step explanation:
If a ball is rolling 5 pounds of force, to stop this ball, we would require 5 pounds of force in the opposite direction.
A force is a pull or push on a body. It can be with contact or without any contact.
Therefore, to stop this body direct an equal and opposite amount of force to it.
Based on Newton's third law of motion "action and reaction forces are equal and opposite in their actions"
