6) Mr. Collins finally decided to take this seriously and put both hands on the rope and applied a 500 N force to the left, while Jared and James still struggled with their 300 N force to the right. What is the net force and direction of motion?

I'm pretty sure the net force is 200 N and the direction of motion is left

Explanation:

500 - 300 = 200 and more force is coming from and pulling toward the left.

i just learnt this recently but i need to look through my notes again

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
