Aforce of 20 newtons is exerted on a chair from its right and a force of 12 newtons is applied from
chair and in what direction will the chair tend to move?
a. the net force acting on the chair is 8 newtons, and the chair moves toward the left.
b. the net force acting on the chair is 32 newtons, and the chair moves toward the left.
c. the net force acting on the chalr is 8 newtons, and the chair moves toward the right:
d. the net force acting on the chair is 32 newtons, and the chair moves toward the right.

The net force acting on the chair is 8 newtons, and the chair moves toward the left.

Explanation:

We can better understand this problem if we analyze it through a free body diagram. This free body diagram is attached as an image.

If we make a sum of forces acting over the chair we can find -20 + 12 = -8 [N]

The minus sign indicates that the chair is moving to the left.

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
