The acceleration is in the direction of the positive force so you will have deceleration in the direction of the negative force.
It's an equation that gives a useful answer.y = x2 + 4 is an equation, but the answer depends on the value of x, and has no units.f = ma (force = mass times acceleration) will give you the numerical value of force f needed to accelerate any object of mass m, at an acceleration value of a. This is a formula.Many people confuse the two:Useful answer with actual dimensional values?Formula.
You add all the forces. Not quite sure what you mean with "no x value is given", but if you don't know ANYTHING about the forces, then you can't calculate the net force either.
Well, honey, in the number 9.56, 5 is in the tenths place. So, if you're looking for its specific place value, it's hanging out in the tenths place like it owns the joint. Hope that clears things up for ya!
