The 10 girls were able to pull the rope toward them with a net force of 50 N. What was the minimum amount of force each of the 10 girls applied to the rope.

That would be the corect answer hope this

Answer form flower;

I'm having some difficulty seeing the diagram clearly.but the question says there's a net inward force on the object.so we know right away,  from newton's 2nd law of motion, thatthat baby is accelerating.  it doesn't even matter which way thenet force is pointing.  if there's any net force, then either theobject's speed or else its direction must be changing.
