GUYS PLEASE HELP ME ANSWER THIS ONE QUESTION Two piano movers are bringing a piano into a home. One mover pushes to the right with
a force of 310 N, while the other pulls to the right as well, but with a force of 270 N. The
force of friction acts to the left, with a magnitude of 190 N. The piano weighs 2500 N.
What is the net force on the piano?

Wish i knew this to !

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction 

Ibelieve the answer is either b or c, but i'm leaning more towards c.hope my answer has you : )
