I have a picture of one person pushing a boulder with 60 N and another person pushing from the same side at 90 N. The friction of the boulder is 40 N. The question asks to find the total force on the boulder.

Question

Is "total force" just the net force in this case or something different?

Answer 1

total force is the sum of all the (directed) forces.

So, yes, I'd say it's the net force.

Answer 2

Is the net force 110 N?

Answer 3

yes. That is, it is 110N in the direction being pushed.
