a 7.0-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?
Since the net force acting on the object is 7.0 N towards the east, and one force is already known to be 10.0 N towards the east, the other force must be acting in the opposite direction (west) in order to reduce the total force to 7.0 N.
To find the magnitude of the other force, we subtract the net force from the known force:
Other force = Known force - Net force
Other force = 10.0 N (east) - 7.0 N (east)
Other force = 3.0 N toward the west
Therefore, the other force acting on the object is 3.0 N towards the west.
