A7.0-kg object is acted on by two forces. one of the forces is 10.0 n acting toward the east. which of the following forces is the other force if the acceleration of the object is 1.0 m/s2 toward the east?

3.0 N acting towards the west

Explanation:

The choices are missing, but we can find the other force by applying Newton's second law:

where

is the net force acting on the object

m is the mass of the object

a is the acceleration

Applied to this question, the equation becomes

where

is the first force (we choose east as positive direction)

is the unknown force

m = 7.0 kg is the mass of the object

is the acceleration (towards the east)

Solving for ,

And the negative sign means that the direction of this force is west.
