A 2.00-kg object moves with constant velocity 3.00 m/s toward the east. Two forces act on the object. The first is a 40.0 N force toward the west. What is the second force that acts on the object?
A)23.0 N east
B)40.0 N east
C)26.7 N east
D)46.0 N east
E)46.0 N west

Question

Quizplus · Accepted Answer

Since the object moves with constant velocity, the net force acting on it must be zero. Therefore, the second force must be equal in magnitude and opposite in direction to the first force (40.0 N west), which means it is 40.0 N east.
